[CMake] Sharing Modules between different installation of CMake

[Nicholas Yue]

Hi,

  I am testing different version of CMake on multiple platform to
ensure my custom modules works fine on all combination.

  I find it troublesome to copy my custom module to all the different
../share/cmake-X.Y/Modules directory

  Is there an alternative to telling CMake that there are additional
Module search path over and above those it normally searches?

Regards
