[CMake] how to make OpenGTL rpm?

[Matthew Woehlke]

I'm trying to build an rpm of OpenGTL, with no success. I added 
'set(CPACK_GENERATOR "TGZ;RPM")' and 'include(CPack)' to the 
CMakeLists.txt, but when I try to build the RPM, it wants to write to 
/usr (ah, shouldn't rpm building NOT need to install first?!), and if I 
run it as root, it installs but yields an empty rpm.

Please help me figure out why it isn't working!
