Is there a safe way to edit a cache variable from

Question

As far as I know, CMake only comes with graphical cache editors. However, I need to edit some cache variables from a shell script. One way is to directly edit CMakeCache.txt but this is not considered safe. Or is it? If not, what is the general practice of editing a cache variable from the command line?

Answer 1

You may call cmake:

• with -D option(s) for set/modify cache variables, or
• with -U option(s) for remove variables from the cache.

Running cmake will cause the project to be reconfigured, but this should be an ultimate purpose of a any cache modification.
