Qt versions and building Subsurface

[Dirk Hohndel]

cmake caches the Qt paths.
So please remove your build directories and invoke scripts/build.sh like this:

(assuming that you are in the src directory)

rm -rf subsurface/build subsurface/build-mobile
CMAKE_PREFIX_PATH=$(pwd)/Qt/5.10.0/clang_64/lib/cmake ./subsurface/scripts/build.sh

This should get the script to pick up Qt5.10 and set up the paths correctly

After checking, it turns out that my build script still uses the system-installed Qt5.5.1 and not Qt5.10 as expected. I need some advice. I installed QT5.10 in folder src/Qt/5.10.0. However, when I build, the build script still uses Qt5.5.1
