[CMake] Cmake module for GNU GSL

[Pablo De Napoli]

Dear Ing. Jan Woetzel,
(and other users in the Cmake list)

I see in a mail in this list, that Felix Woelk and Jan Woetzel
has writen a module for finding GSL for CMake:

http://www.cmake.org/pipermail/cmake/2006-March/008628.html

I think that It would be great if that module could be integrated into 
the  next release of Cmake, so that we have a a standard module 
for finding that libray.
