"exisitng" in the sense that Creator created it, yes.

This did it - thank you.

I guess my disconnect was twofold:

- When setting up cmake initially, the kits don't have any generator set,
so it results in confusion. When I added cmake and tried to run it on my
project it created the build dir, so CMAKE_GENERATOR ended up empty. Maybe
when setting cmake for the first time it in the prefs Creator should
reminder the developer that "The following kits are not set up properly to
use cmake. You need to set the generators." or something like that.

- The error message (to me - a non-cmake guy) didn't help (or maybe I was
coffee-deprived enough that it didn't make sense). Maybe having it output
the values that are different would help? And possibly offer a solution to
the user? "Change the project's setting in its CMakeCache.txt or change the
kit setting in the preferences."

Anyway - it's going now. Thanks a lot Tobias!
