[CMake] cmake-3.5.1 for AIX 5.3 TL7 and later

[Michael Felt]

Just completed the build for cmake on a AIX 5.3 system, so the packaging 
will be accepted also by AIX 6.1, AIX 7.1 and AIX 7.2.

The package is available via: http://www.aixtools.net/index.php/cmake

Note: still have to update the link - if you are too fast you will see 
my packaging for cmake-2.8.11.2
