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.
There is no such tool. There are also problems with such a tool. The
main problem is the if statement. To get complete docs for a project
you would have to evaluate each if both true and false to make sure you
found all possible cache values for a project. It has come up on the
list a few times, but no general solution has been discovered.
