Not sure I understand the problem but you can use CMAKE_PREFIX_PATH to
help FindQt4 locate the qmake you want it to find. This means you need
to have the qmake for your cross-compile target available from your
build host, but your 3rd party libraries are already in a single common
repository, right?
