CMake ninja generator may not create *.dir output directories
before the first compilation pass, causing 'fatal error: opening
dependency file ... No such file or directory' during the Qt host
tools build (moc, uic, qtwaylandscanner). Add a find+mkdir loop
between cmake configure and cmake --build to pre-create them.
