I have generated .h and .c files which must be compiled as C++ files with Visual Studio.
I heard I could do something like set_source_files_properties( ${SOURCES} PROPERTIES LANGUAGE "CXX" ). In parallel, I have read that I should not do that as it should used only in exotic situations.
So, what is the best way to force CMake to generate VS projects which compiles C files as C++ files?
PS: renaming the generated files is not an option.
I have been using the individual properties (most likely you can also set directory properties – but this is not as fine grained) without any problems. Not for setting the language though (but why should it be any different?):
This works under Linux and Windows and doesn’t seem to pose any problems. What have you heard that makes you hesitate?
