Overriding 'up-to-date' status in cmake

I’m trying to reinstall Root 5 on a system and cmake won’t re-copy a lot of files because it reports that the files are up to date.

How do I override this and force a full reinstall?

Try to run “make distclean” or maybe better “make maintainer-clean”.

Hi. CMake provided a environment variable to control exactly this: CMAKE_INSTALL_ALWAYS. I never tried myself but according to the (old) documentation should do what you want cmake.org/Wiki/CMake_Useful_Variables
