Thinking about it again...

https://developer.apple.com/library/mac/documentation/Darwin/Reference/Manpages/man5/compat.5.html

seems we can also pass -DCMAKE_OSX_DEPLOYMENT_TARGET='10.6' which might
be the more correct one.

For that, we just need to agree on the lowest OSX version to support
(e.g. the one that Qt supports?).

Also note - some frameworks (e.g. kio) also want:

    "-DCMAKE_C_FLAGS='-D_DARWIN_C_SOURCE'"
    "-DCMAKE_REQUIRED_DEFINITIONS='-D_DARWIN_C_SOURCE'"

The last one is required as CMake doesn't seem to honor CXX_FLAGS when
running configure tests.
