Read the version from build_scripts/compile_version_string.txt

The CMake build had the version hard-coded as 5.7.4, while the qmake build
read it from compile_version_string.txt (5.8.17-release). The stale number
also made the version check report an update. As in the qmake build, the
full string becomes APPLICATION_VERSION and its numeric part the project
version.
