[CMake] Using a header only library that links uses Objective-C headers

[Florent Castelli]

You don't compile a header only library (unless you're talking about 
precompiled headers, which I think you don't).

What you need is compiling the sources using it as Objective C.
Which is a matter of adding target_compile_options(<target> PRIVATE 
"-ObjC") on the target with the sources if I remember correctly.
