This looks wrong to me.
In general CMAKE_PREFIX_PATH should contain only the base install directory of
packages, and not point into the library dir etc. So it should more look
something like this:
set(CMAKE_PREFIX_PATH "${QT_PREFIX}")
But actually this should be left to the user, since he knows where Qt is used
(or is supposed to know).

Yes. A "normal" set() call overrides values coming from the cache.

Ehm, doesn't testpath in the CMakeCache.txt have the contents of
CMAKE_MODULE_PATH from the CMakeLists.txt ?
