Since commit v3.9.0-rc4~3^2~1 (VS: Fix target_compile_options for CUDA, 2017-06-21), the evaluation of `COMPILE_LANGUAGE` receives the proper language. The set of compile flags used for a target's C and C++ sources is based on the linker language. By default this is always the C++ flags if any C++ sources appear in the target, and otherwise the C flags. Therefore we can define the `COMPILE_LANGUAGE` generator expression in `COMPILE_OPTIONS` to match the selected language. This is not exactly the same as for other generators, but is the best VS can do. It is also sufficient for many use cases since the set of allowed flags for C and C++ is almost the same in Visual Studio. Furthermore, since the VS generator moves many of the flags to declarative `.vcxproj` elements, it will automatically avoid passing C++ flags for C sources. Issue: #17435
