Does CMake even provide a way of marking variables as deprecated? Simply 
making the old name an alias for the new doesn't quite work, as we need to 
maintain compatibility on the command line as well as in the CMakeLists files.

Hum. I went for that to try to make it at least partially interchangable with 
GNUInstallDirs.cmake. Perhaps that wasn't such a bright idea - at least, I 
should maybe have made the ones that *don't* appear in GNUInstallDirs have a 
different prefix.

I agree that the variables are a bit of a mess. It's... well, not the approach 
I would have taken if I had started less close to the source compatibility 
cut-off date for KF5.
