That was merged as a tab into the code style page

"CMake version  is unsupported”

Between “version” and “is” there should be a version number, so it looks like the version parsing failed there too. 
Or, since especially the cmake version doesn’t seem unusual, maybe Qt Creator failed to execute the processes?

Some things to look at:

- What do you see in Tools > Options > Kits > CMake ? Is the right cmake binary there, is any error shown, is the version number shown?
- What does the “CMake Tool” setting in the kit say?
- Maybe running Qt Creator from a terminal shows some enlightening output, or maybe it does when setting QT_LOGGING_RULES=“qtc.utils.qtcprocess.debug=true”.
