Summary:                    FindX11.cmake does not respect pkg-config and
therefore fails to obtain proper cflags for libXft
Description: 
We are moving freetype2 header into ABI-specific location in order to support
multilib properly. The freetype2.pc specifies correct include path, and
libXft.pc uses 'Requires.private' on freetype2.

Therefore:

$ pkg-config --cflags xft
-I/usr/lib64/freetype2/include/freetype2 -I/usr/lib64/freetype2/include  

However, CMake does not use pkg-config but some hard-to-understand discovery
logic which finds libXft properly but makes applications using it fail to build
due to the necessity of having freetype2 include path as well.

Steps to Reproduce: 
1. build and install freetype2 with --includedir=/non-standard-location,
2. build and install libXft,
3. try to build any application using cmake & libXft, e.g. slim.
