Basically, you are using cmake incorrectly.  You should not be using 
environment variables in a cmake
project directly.  You should only use them for place for FIND_* to look 
for things.   You should
not depend on having the environment set before running cmake.  You are 
asking for trouble with
builds.   For example:

1/ setenv .... ; cmake ;   make
2  cvs update
3 start a new shell and forget the setenv
4. make  (this runs cmake because a file changed in the cvs update) , it 
creates new makefiles that
don't work.

CMake should be used to cache variables that store locations of include 
and library paths that
were discovered by cmake.
