[Cmake] feature request - separate user and system cmake cach e files

[Wheeler, Frederick W (Research)]

Tony,

I generally accomplish what you describe by deleting the CMakeCache.txt file, replacing it with a
hand generated file that has the settings I want, and then running cmake.  Below is an example
plucked from one of my build scripts.  You can also append to the end of a CMakeCache.txt file.  The
settings made at the end override those that come before.  I never use the CMake GUI.  Perhaps there
is some additional difficulty in doing this with the GUI?

Subject: [Cmake] feature request - separate user and system cmake cache files


I apologize if this has already been brought up.  I think it would be helpful if the CMakeCache.txt
file can be split into a user file and a system file.  The motivation for the request is that I have
been setting up several build environments, and typing in the same stuff over and over is getting old
very quickly.  It'd be nice if I can just copy the user config file, make a few modifications, and
then rerun cmake to regenerate the system configs.  This would be useful for setting up testing
environments.  In addition, having separate cache files would make updating src code to new versions
easier and less prone to dirty cache, as I'd only need to blow away the system cache.

Thanks.

Tony
