[CMake] Where to put own FindXXX.cmake

[Olivier Tournaire]

Hi all,

I sometimes have to define my own Findxxx.cmake, or update the ones 
coming with the package. I leave them or put them in the Modules 
directory. However, when I want to update my CMake version, I guess the 
files in the Modules directory are deleted or replace by the ones in the 
new distribution.

So, I would like to know how can I set something in CMake to give it 
another directory to search for my own Findxxx.cmake.

Best regards,

Olivier
