The above all happens inside files loaded by find_package.  The
problem is that they are being loaded through a path starting
in "/" and using that to compute the import prefix relative to
themselves.  This process is a victim of the real problem, not
the cause.

We need to figure out what tells find_package to look for and
load KActivitiesConfig.cmake from a path with no drive letter
in the first place.
