RetroPie setup reverting cmake to 3.13

[akamming]

Hi,

for another software i have on my rpi i need cmake to be at least on level 3.16. So i have the latest (3.17.1) installed by following the instructions on cmake.org (basically uninstalling the .deb packages from raspbian itsel, compiling from source and the install with a " make install" command)

i noticed however that when i run the Update command from the RetroPie setup script, cmake is reverted to 3.13 again. Apparently it does not detect that a higher version is already installed, cause i also noticed that cmake and cmake-data are installed again as raspbian packages.

Is there some way to prevent this when running an update?

Or even better: Could the RetroPie Setup be modified, so it detects cmake is already present and on required level, so it does not install the raspbian packages?

It does not detect it, because it's not installed from a .deb package. RetroPie installs the cmake package that's available in the distro - whatever version is available in the Raspbian repositories.

As a general rule when installing from source - in order to not get your installation overwritten by a distro package, don't install into the system directories (/usr/bin, /usr/sbin, etc.) - use /usr/local or /opt.
