Update SetupQt.cmake

Browse source 
This change allows -DQT_CMAKE_PREFIX_PATH to function again. Previously, set(QT_CMAKE_PREFIX_PATH "$ENV{QT_CMAKE_PREFIX_PATH}") always ran, which overrode QT_CMAKE_PREFIX_PATH every time on cmake. This proposed change now only uses the environment variable if DQT_CMAKE_PREFIX_PATH is not specified.
