Cannot parse Qt for Android 6.0.0 with CMake

When opening a CMake project with a Qt for Android 6.0.0 kit, parsing fails (log attached). 

Qt 6.0 build with CMake includes a script wrapper for CMake under <Install_prefix>/bin/qt-cmake, that can be used to configure only, but cannot be used for building, and then it's not used to replace the CMake tool defined already in QC.

Qt 6.0 CMake for Android requires QT_HOST_PATH to be provided for CMake to properly configure, which QC doesn't know about.
