Hey,
thanks for the feedback. Well, converting my whole build system [1][2] to qmake would be an enormous task for little to no gain at all. I'd rather special-case for this in configure and implement the shell-script hackery. Maybe I'll include a dummy project file, let qmake generate a Makefile and extract the required information from it.
That brings me to another question: why are the Qt5 development tools (moc, uic, qmake etc.) not installed as ${MXE}/usr/bin/${host}-${tool} as well? They're only available as ${MXE}/usr/${host}/bin/${tool}. At least qmake is host-specific regarding where it looks for its .prl files, and at the moment I have to tell configure where those binaries are manually (or manipulate PATH and prepend that directory along with the general MXE bin directory).
Kind regards,
mosu
