Merge pull request #1133 from DioEgizio/bump-mac-11.0

Noticed only now that Qt 6.5 bumps the macOS requirement to macOS 11.
This was basically already effective in prism since with the Qt 6.5 bump pr macOS 10.15 user's wouldn't be able to run this, but updating the requirement here makes it more clear for the end user trying to run prism on macOS 10.15

+# Contributions Guidelines
+
+## Code formatting
+
+Try to follow the existing formatting.
+If there is no existing formatting, you may use `clang-format` with our included `.clang-format` configuration.
+
+In general, in order of importance:
+
+- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
+- Prefer readability over dogma.
+- Keep to the existing formatting.
+- Indent with 4 space unless it's in a submodule.
+- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.
+
+## Signing your work
+
+In an effort to ensure that the code you contribute is actually compatible with the licenses in this codebase, we require you to sign-off all your contributions.
+
+This can be done by appending `-s` to your `git commit` call, or by manually appending the following text to your commit message:
+
+```
+<commit message>
+
+Signed-off-by: Author name <Author email>
+```
+
+By signing off your work, you agree to the terms below:
+
+```
+Developer's Certificate of Origin 1.1
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+```
+
+These terms will be enforced once you create a pull request, and you will be informed automatically if any of your commits aren't signed-off by you.
+
+As a bonus, you can also [cryptographically sign your commits][gh-signing-commits] and enable [vigilant mode][gh-vigilant-mode] on GitHub.

-If you want to build PolyMC yourself, check [BUILD.md](BUILD.md) for build instructions.
-
-## Code formatting
-
-Just follow the existing formatting.
-
-In general, in order of importance:
-
-- Make sure your IDE is not messing up line endings or whitespace and avoid using linters.
-- Prefer readability over dogma.
-- Keep to the existing formatting.
-- Indent with 4 space unless it's in a submodule.
-- Keep lists (of arguments, parameters, initializers...) as lists, not paragraphs. It should either read from top to bottom, or left to right. Not both.

 ## Forking/Redistributing/Custom builds policy
 
-Do whatever you want, we don't care. Just follow the license. If you have any questions about this feel free to ask in an issue.
+We don't care what you do with your fork/custom build as long as you follow the terms of the [license](LICENSE) (this is a legal responsibility), and if you made code changes rather than just packaging a custom build, please do the following as a basic courtesy:
+
+- Make it clear that your fork is not PrismLauncher and is not endorsed by or affiliated with the PrismLauncher project (<https://prismlauncher.org>).
+- Go through [CMakeLists.txt](CMakeLists.txt) and change PrismLauncher's API keys to your own or set them to empty strings (`""`) to disable them (this way the program will still compile but the functionality requiring those keys will be disabled).
+
+If you have any questions or want any clarification on the above conditions please make an issue and ask us.
+
+Be aware that if you build this software without removing the provided API keys in [CMakeLists.txt](CMakeLists.txt) you are accepting the following terms and conditions:
+
+- [Microsoft Identity Platform Terms of Use](https://docs.microsoft.com/en-us/legal/microsoft-identity-platform/terms-of-use)
+- [CurseForge 3rd Party API Terms and Conditions](https://support.curseforge.com/en/support/solutions/articles/9000207405-curse-forge-3rd-party-api-terms-and-conditions)
+
+If you do not agree with these terms and conditions, then remove the associated API keys from the [CMakeLists.txt](CMakeLists.txt) file by setting them to an empty string (`""`).

-# - Functions to help assemble a standalone bundle application.
-# A collection of CMake utility functions useful for dealing with .app
-# bundles on the Mac and bundle-like directories on any OS.
-#
-# The following functions are provided by this module:
-#   fixup_bundle
-#   copy_and_fixup_bundle
-#   verify_app
-#   get_bundle_main_executable
-#   get_dotapp_dir
-#   get_bundle_and_executable
-#   get_bundle_all_executables
-#   get_item_key
-#   clear_bundle_keys
-#   set_bundle_key_values
-#   get_bundle_keys
-#   copy_resolved_item_into_bundle
-#   copy_resolved_framework_into_bundle
-#   fixup_bundle_item
-#   verify_bundle_prerequisites
-#   verify_bundle_symlinks
-# Requires CMake 2.6 or greater because it uses function, break and
-# PARENT_SCOPE. Also depends on GetPrerequisites.cmake.
-#
-#  FIXUP_BUNDLE(<app> <libs> <dirs>)
-# Fix up a bundle in-place and make it standalone, such that it can be
-# drag-n-drop copied to another machine and run on that machine as long as all
-# of the system libraries are compatible.
-#
-# If you pass plugins to fixup_bundle as the libs parameter, you should install
-# them or copy them into the bundle before calling fixup_bundle. The "libs"
-# parameter is a list of libraries that must be fixed up, but that cannot be
-# determined by otool output analysis. (i.e., plugins)
-#
-# Gather all the keys for all the executables and libraries in a bundle, and
-# then, for each key, copy each prerequisite into the bundle. Then fix each one
-# up according to its own list of prerequisites.
-#
-# Then clear all the keys and call verify_app on the final bundle to ensure
-# that it is truly standalone.
-#
-#  COPY_AND_FIXUP_BUNDLE(<src> <dst> <libs> <dirs>)
-# Makes a copy of the bundle <src> at location <dst> and then fixes up the
-# new copied bundle in-place at <dst>...
-#
-#  VERIFY_APP(<app>)
-# Verifies that an application <app> appears valid based on running analysis
-# tools on it. Calls "message(FATAL_ERROR" if the application is not verified.
-#
-#  GET_BUNDLE_MAIN_EXECUTABLE(<bundle> <result_var>)
-# The result will be the full path name of the bundle's main executable file
-# or an "error:" prefixed string if it could not be determined.
-#
-#  GET_DOTAPP_DIR(<exe> <dotapp_dir_var>)
-# Returns the nearest parent dir whose name ends with ".app" given the full
-# path to an executable. If there is no such parent dir, then simply return
-# the dir containing the executable.
-#
-# The returned directory may or may not exist.
-#
-#  GET_BUNDLE_AND_EXECUTABLE(<app> <bundle_var> <executable_var> <valid_var>)
-# Takes either a ".app" directory name or the name of an executable
-# nested inside a ".app" directory and returns the path to the ".app"
-# directory in <bundle_var> and the path to its main executable in
-# <executable_var>
-#
-#  GET_BUNDLE_ALL_EXECUTABLES(<bundle> <exes_var>)
-# Scans the given bundle recursively for all executable files and accumulates
-# them into a variable.
-#
-#  GET_ITEM_KEY(<item> <key_var>)
-# Given a file (item) name, generate a key that should be unique considering
-# the set of libraries that need copying or fixing up to make a bundle
-# standalone. This is essentially the file name including extension with "."
-# replaced by "_"
-#
-# This key is used as a prefix for CMake variables so that we can associate a
-# set of variables with a given item based on its key.
-#
-#  CLEAR_BUNDLE_KEYS(<keys_var>)
-# Loop over the list of keys, clearing all the variables associated with each
-# key. After the loop, clear the list of keys itself.
-#
-# Caller of get_bundle_keys should call clear_bundle_keys when done with list
-# of keys.
-#
-#  SET_BUNDLE_KEY_VALUES(<keys_var> <context> <item> <exepath> <dirs>
-#                        <copyflag>)
-# Add a key to the list (if necessary) for the given item. If added,
-# also set all the variables associated with that key.
-#
-#  GET_BUNDLE_KEYS(<app> <libs> <dirs> <keys_var>)
-# Loop over all the executable and library files within the bundle (and given
-# as extra <libs>) and accumulate a list of keys representing them. Set
-# values associated with each key such that we can loop over all of them and
-# copy prerequisite libs into the bundle and then do appropriate
-# install_name_tool fixups.
-#
-#  COPY_RESOLVED_ITEM_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
-# Copy a resolved item into the bundle if necessary. Copy is not necessary if
-# the resolved_item is "the same as" the resolved_embedded_item.
-#
-#  COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE(<resolved_item> <resolved_embedded_item>)
-# Copy a resolved framework into the bundle if necessary. Copy is not necessary
-# if the resolved_item is "the same as" the resolved_embedded_item.
-#
-# By default, BU_COPY_FULL_FRAMEWORK_CONTENTS is not set. If you want full
-# frameworks embedded in your bundles, set BU_COPY_FULL_FRAMEWORK_CONTENTS to
-# ON before calling fixup_bundle. By default,
-# COPY_RESOLVED_FRAMEWORK_INTO_BUNDLE copies the framework dylib itself plus
-# the framework Resources directory.
-#
-#  FIXUP_BUNDLE_ITEM(<resolved_embedded_item> <exepath> <dirs>)
-# Get the direct/non-system prerequisites of the resolved embedded item. For
-# each prerequisite, change the way it is referenced to the value of the
-# _EMBEDDED_ITEM keyed variable for that prerequisite. (Most likely changing to
-# an "@executable_path" style reference.)
-#
-# This function requires that the resolved_embedded_item be "inside" the bundle
-# already. In other words, if you pass plugins to fixup_bundle as the libs
-# parameter, you should install them or copy them into the bundle before
-# calling fixup_bundle. The "libs" parameter is a list of libraries that must
-# be fixed up, but that cannot be determined by otool output analysis. (i.e.,
-# plugins)
-#
-# Also, change the id of the item being fixed up to its own _EMBEDDED_ITEM
-# value.
-#
-# Accumulate changes in a local variable and make *one* call to
-# install_name_tool at the end of the function with all the changes at once.
-#
-# If the BU_CHMOD_BUNDLE_ITEMS variable is set then bundle items will be
-# marked writable before install_name_tool tries to change them.
-#
-#  VERIFY_BUNDLE_PREREQUISITES(<bundle> <result_var> <info_var>)
-# Verifies that the sum of all prerequisites of all files inside the bundle
-# are contained within the bundle or are "system" libraries, presumed to exist
-# everywhere.
-#
-#  VERIFY_BUNDLE_SYMLINKS(<bundle> <result_var> <info_var>)
-# Verifies that any symlinks found in the bundle point to other files that are
-# already also in the bundle... Anything that points to an external file causes
-# this function to fail the verification.

+ECMQueryQt
+---------------
+This module can be used to query the installation paths used by Qt.
+
+For Qt5 this uses ``qmake``, and for Qt6 this used ``qtpaths`` (the latter has built-in
+support to query the paths of a target platform when cross-compiling).
+
+This module defines the following function:
+::
+
+    ecm_query_qt(<result_variable> <qt_variable> [TRY])
+
+Passing ``TRY`` will result in the method not making the build fail if the executable
+used for querying has not been found, but instead simply print a warning message and
+return an empty string.
+
+Example usage:
+
+.. code-block:: cmake
+
+    include(ECMQueryQt)
+    ecm_query_qt(bin_dir QT_INSTALL_BINS)
+
+If the call succeeds ``${bin_dir}`` will be set to ``<prefix>/path/to/bin/dir`` (e.g.
+``/usr/lib64/qt/bin/``).
+
+Since: 5.93

-# - Functions to analyze and list executable file prerequisites.
-# This module provides functions to list the .dll, .dylib or .so
-# files that an executable or shared library file depends on. (Its
-# prerequisites.)
-#
-# It uses various tools to obtain the list of required shared library files:
-#   dumpbin (Windows)
-#   objdump (MinGW on Windows)
-#   ldd (Linux/Unix)
-#   otool (Mac OSX)
-# The following functions are provided by this module:
-#   get_prerequisites
-#   list_prerequisites
-#   list_prerequisites_by_glob
-#   gp_append_unique
-#   is_file_executable
-#   gp_item_default_embedded_path
-#     (projects can override with gp_item_default_embedded_path_override)
-#   gp_resolve_item
-#     (projects can override with gp_resolve_item_override)
-#   gp_resolved_file_type
-#     (projects can override with gp_resolved_file_type_override)
-#   gp_file_type
-# Requires CMake 2.6 or greater because it uses function, break, return and
-# PARENT_SCOPE.
-#
-#  GET_PREREQUISITES(<target> <prerequisites_var> <exclude_system> <recurse>
-#                    <exepath> <dirs>)
-# Get the list of shared library files required by <target>. The list in
-# the variable named <prerequisites_var> should be empty on first entry to
-# this function. On exit, <prerequisites_var> will contain the list of
-# required shared library files.
-#
-# <target> is the full path to an executable file. <prerequisites_var> is the
-# name of a CMake variable to contain the results. <exclude_system> must be 0
-# or 1 indicating whether to include or exclude "system" prerequisites. If
-# <recurse> is set to 1 all prerequisites will be found recursively, if set to
-# 0 only direct prerequisites are listed. <exepath> is the path to the top
-# level executable used for @executable_path replacment on the Mac. <dirs> is
-# a list of paths where libraries might be found: these paths are searched
-# first when a target without any path info is given. Then standard system
-# locations are also searched: PATH, Framework locations, /usr/lib...
-#
-#  LIST_PREREQUISITES(<target> [<recurse> [<exclude_system> [<verbose>]]])
-# Print a message listing the prerequisites of <target>.
-#
-# <target> is the name of a shared library or executable target or the full
-# path to a shared library or executable file. If <recurse> is set to 1 all
-# prerequisites will be found recursively, if set to 0 only direct
-# prerequisites are listed. <exclude_system> must be 0 or 1 indicating whether
-# to include or exclude "system" prerequisites. With <verbose> set to 0 only
-# the full path names of the prerequisites are printed, set to 1 extra
-# informatin will be displayed.
-#
-#  LIST_PREREQUISITES_BY_GLOB(<glob_arg> <glob_exp>)
-# Print the prerequisites of shared library and executable files matching a
-# globbing pattern. <glob_arg> is GLOB or GLOB_RECURSE and <glob_exp> is a
-# globbing expression used with "file(GLOB" or "file(GLOB_RECURSE" to retrieve
-# a list of matching files. If a matching file is executable, its prerequisites
-# are listed.
-#
-# Any additional (optional) arguments provided are passed along as the
-# optional arguments to the list_prerequisites calls.
-#
-#  GP_APPEND_UNIQUE(<list_var> <value>)
-# Append <value> to the list variable <list_var> only if the value is not
-# already in the list.
-#
-#  IS_FILE_EXECUTABLE(<file> <result_var>)
-# Return 1 in <result_var> if <file> is a binary executable, 0 otherwise.
-#
-#  GP_ITEM_DEFAULT_EMBEDDED_PATH(<item> <default_embedded_path_var>)
-# Return the path that others should refer to the item by when the item
-# is embedded inside a bundle.
-#
-# Override on a per-project basis by providing a project-specific
-# gp_item_default_embedded_path_override function.
-#
-#  GP_RESOLVE_ITEM(<context> <item> <exepath> <dirs> <resolved_item_var>)
-# Resolve an item into an existing full path file.
-#
-# Override on a per-project basis by providing a project-specific
-# gp_resolve_item_override function.
-#
-#  GP_RESOLVED_FILE_TYPE(<original_file> <file> <exepath> <dirs> <type_var>)
-# Return the type of <file> with respect to <original_file>. String
-# describing type of prerequisite is returned in variable named <type_var>.
-#
-# Use <exepath> and <dirs> if necessary to resolve non-absolute <file>

-# files (SRC) and adds the given resource files (RCS) to the jar file.
-# If only resource files are given then just a jar file is created.
-#
-# Additional instructions:
-#   To add compile flags to the target you can set these flags with
-#   the following variable:
-#
-#       set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
-#
-#   To add a path or a jar file to the class path you can do this
-#   with the CMAKE_JAVA_INCLUDE_PATH variable.
-#
-#       set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
-#
-#   To use a different output name for the target you can set it with:

-#       set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
-#       add_jar(foobar foobar.java)
-#
-#   To use a different output directory than CMAKE_CURRENT_BINARY_DIR
-#   you can set it with:
-#
-#       set(CMAKE_JAVA_TARGET_OUTPUT_DIR ${PROJECT_BINARY_DIR}/bin)
-#
-#   To define an entry point in your jar you can set it with:
-#
-#       set(CMAKE_JAVA_JAR_ENTRY_POINT com/examples/MyProject/Main)
-#
-#   To add a VERSION to the target output name you can set it using
-#   CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
-#   shibboleet-1.0.0.jar and will create a symlink shibboleet.jar
-#   pointing to the jar with the version information.
-#
-#       set(CMAKE_JAVA_TARGET_VERSION 1.2.0)

-#       install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
-#       install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
-#
-#    If a single target needs to produce more than one jar from its
-#    java source code, to prevent the accumulation of duplicate class
-#    files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
-#    to calling the add_jar() function:

-#                      it.
-#   CLASS_DIR          The directory where the class files can be found. For

-# There are two main signatures for create_javadoc. The first
-# signature works with package names on a path with source files:
-#
-#   Example:
-#   create_javadoc(my_example_doc
-#     PACKAGES com.exmaple.foo com.example.bar
-#     SOURCEPATH "${CMAKE_CURRENT_SOURCE_DIR}"
-#     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
-#     WINDOWTITLE "My example"
-#     DOCTITLE "<h1>My example</h1>"
-#     AUTHOR TRUE
-#     USE TRUE
-#     VERSION TRUE
-#   )
-#
-# The second signature for create_javadoc works on a given list of
-# files.
-#
-#   create_javadoc(<VAR>
-#                  FILES file1 [file2 ...]
-#                  [CLASSPATH <classpath>]
-#                  [INSTALLPATH <install path>]
-#                  [DOCTITLE "the documentation title"]
-#                  [WINDOWTITLE "the title of the document"]
-#                  [AUTHOR TRUE|FALSE]
-#                  [USE TRUE|FALSE]
-#                  [VERSION TRUE|FALSE]
-#                 )
-#
-# Example:
-#   create_javadoc(my_example_doc
-#     FILES ${example_SRCS}
-#     CLASSPATH ${CMAKE_JAVA_INCLUDE_PATH}
-#     WINDOWTITLE "My example"
-#     DOCTITLE "<h1>My example</h1>"
-#     AUTHOR TRUE
-#     USE TRUE
-#     VERSION TRUE
-#   )
-#
-# Both signatures share most of the options. These options are the
-# same as what you can find in the javadoc manpage. Please look at
-# the manpage for CLASSPATH, DOCTITLE, WINDOWTITLE, AUTHOR, USE and
-# VERSION.
-#
-# The documentation will be by default installed to
-#
-#   ${CMAKE_INSTALL_PREFIX}/share/javadoc/<VAR>
-#
-# if you don't set the INSTALLPATH.
