[CMake] Getting a list of the defined CMake cache variables along with properties and documentation?

[Bartlett, Roscoe A]

Hello,

Is there a way in a CMakeLists.txt file to get a list of all of the defined CMake cache variables, get their properties, and their documentation?  I would like to have this so that I can build more general documentation for our CMake project.  I could of course just parse the CMakeCache.txt file myself but if there is a way to do this in CMake then that might be better.  Otherwise, I will need to create a tool that would do a configure, then read the CMakeCache.txt file and build documentation output like you would see for our current autotools build system.

Thanks,

- Ross
