Summary:                    CMake support for the Linux x86-64 32-bit ABI
(x32-abi)
Description: 
Currently CMake assumes library files can be located in
${CMAKE_INSTALL_PREFIX}/lib{64}, or otherwise on the system in /lib{64},
/usr/lib{64} etc.  This isn't the case with x32-abi, where library directories
are postfixed with x32, for example: ${CMAKE_INSTALL_PREFIX}/libx32

This results in CMake modules being unable to locate their resources, including
failure during the configuration of CMake itself after initial bootstrap if
CMAKE_INSTALL_PREFIX and individual *_DIR=/usr/libx32/cmake/* variables aren't
manually provided.

Steps to Reproduce: 
Build CMake from source on x32.  Attempt to build projects with CMake.

Additional Information: 
The attached patch is from pld-linux, a similar patch also exists for Gentoo
Linux.  This gives CMake the extra knowledge necessary to successfully locate
the library paths on x32-abi.

Perhaps, in the future a centralised CMake facility could provide system library
paths?
