Using this variable is problematic is the user has several versions of Qt installed on their system. There is no way to know ahead of time if the Qt version pointed to by QTDIR matches the toolchain that is being targeted. The Qt installation path can still be easily specified if it's not found by CMake by setting the Qt5_DIR cache variable after the initial configuration run, so this shouldn't present an usability issue.
