Ah, never came across that part before. What happens if you explicitly
disable searching the package registry?

Hmm, at this point I'd probably try cmake --trace and/or --debug-outpu
and maybe also the output of --system-information to find out why
cmake decides to load the config file from that location.

Oh and I assume that your client thats using the config has its own
build-directory, i.e. something like ~/build/<client>/ and there's no
CMakeCache.txt in ~/build/
