CMake: Show configuration summary on first configuration

Browse Source 
or when feature changes are detected, even when the log-level is set
to NOTICE (which is the default for non-developer-builds).

We want to show the summary during the first configuration so we don't
force users to look into the config.summary file.

We want not to show the summary upon reconfigurations, to keep regular
reconfigurations as quiet as possibe, so it's easy to notice any new
warnings.
