I'd double check and make sure that __APPLE__ isn't getting accidentally 
  defined somehow by something you're #including.


Alternatively, make a small Hello World project for CMake and verify 
that it's actually defining __APPLE__ when you generate on FreeBSD.

CMakeLists.txt:
ADD_EXECUTABLE(hello hello.cc)

hello.cc:

#include <iostream>
int main()
#ifdef __APPLE__
    std::cout << "Apple is defined!" << std::endl;
#endif
    return 0;
}
