thanks,
now I don't have an error for finding the cmake module.

I still have a question, if I want to check if the paths exist, the only 
way to call this custom.cmake is to add  MACRO(MACRO_FINDQGLVIEWER) and
ENDMACRO(MACRO_FINDQGLVIEWER) in the script than to call this macro am I 
correct ? or is there a simpler way?
Thanks,
