Is there a way to increase the variable name column width for the ccmake tool?
No, there is an issue regarding that: https://gitlab.kitware.com/cmake/cmake/-/issues/22370
I have an old branch (https://gitlab.kitware.com/sjoubert/cmake/-/tree/ccmake-improve-cache-display) where I started addressing that and improving the ccmake display overall (with dynamic column name width add key entry to manually resize it) but I never got to finish it
