* Fix C compiler warnings about C++ flags
```
cc1: warning: command line option ‘-Wnon-virtual-dtor’ is valid for C++/ObjC++ but not for C
cc1: warning: command line option ‘-Woverloaded-virtual’ is valid for C++/ObjC++ but not for C
```
... using the generator expression `$<COMPILE_LANGUAGE:CXX>`.
* COMPILE_LANGUAGE is new in CMake 3.3
See https://cmake.org/cmake/help/v3.3/release/3.3.html
