The declarations in my_c_header.h are surrounded by
#if defined(__cplusplus)
extern "C" {
#endif
// functions and stuff declarations
#if defined(__cplusplus)
}
#endif
So i'm not sure about whether it's taken into account or not, and how to
have CMake take it into account when I compile my library as C.
