In a Qt build that was configured with INSTALL_MKSPECSDIR set to something different than INSTALL_DATADIR, the qmake property QT_HOST_DATA was wrong. Consequently, mkspecs could not be loaded, rendering qmake dysfunctional. The reason was that we considered every QT_HOST_xxx property to have the same value as QT_INSTALL_xxx in a non-cross build. This is not true for QT_HOST_DATA, because users might want to set INSTALL_DATADIR to "foo" but INSTALL_MKSPECSDIR to "bar/mkspecs". Move the unused determination of the host data dir to the QtLibraryInfo lib and handle QT_HOST_DATA specially. Fixes: QTBUG-94591 Pick-to: 6.2 Change-Id: I2c44cda8405ff1d14391254fcd1d9b1361cb5855 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
