# /EHs Enables stack unwind semantics for standard C++ exceptions to ensure stackframes are unwound
# and object deconstructors are called when an exception is caught.
# without it memory leaks and a warning is printed
# /EHc tells the compiler to assume that functions declared as extern "C" never throw a C++ exception
# This appears to not always be a defualt compiler option in CMAKE
