If we configure module that is already installed it's expected that
tests use the build directory to resolve all the depdencies, but not
the install directory. This is especially sensetive if the module cmake
scripts were changed.
This changes the order of find_<package|dependency> PATHS that are
used to locate Qt package. QT_EXAMPLES_CMAKE_PREFIX_PATH now is used at
first, so we guarantee that we look into the build directory at
first place. This trick only works if build directory is added to
CMAKE_FIND_ROOT_PATH. The reason for that is the internal CMake logic
that tries to relocate the search PATHs and put the paths that are
subdirs of or exact CMAKE_FIND_ROOT_PATH higher in search list.
