Thanks Brad

yes, and that's the point.

I've found my mistake, I had set the CMAKE_OSX_DEPLOYMENT_TARGET and \
CMAKE_OSX_SYSROOT between the check_cxx_source_compiles() calls and the \
add_subdirectory() calls. I moved the CMAKE_OSX_DEPLOYMENT_TARGET and \
CMAKE_OSX_SYSROOT initialization on top of the check_cxx_source_compiles() calls and \
everthing is working as expected.

So, in my situation the order is:
1.) CMAKE_OSX_DEPLOYMENT_TARGET and CMAKE_OSX_SYSROOT
2.) check_cxx_source_compiles() and other platform checks
3.) add_subdirectory() and other stuff

Best Regards
Roman
