for possible version checks in build systems which expect the variable
prefix to match that of the other variables

using pkg-config search as primary method with fallback to path lookup,
this may result in overlinking however if libraries require additional
include paths (as is the case with PulseAudio) with this change that will
not be a problem.
it will also reduce the lookups done during configuration/build since path
lookups will not be done, unless pkg-config lookup does not set the
required variables.

this includes QtWebKit support removal since it is not going to be
maintained, fancy headers removal, CMake modules rewrite/removal
and removing conditionals from the build system. Pre-processor
definitions checks are still in place on purpose
