Yes, that's what I'm trying to do -- well, I'm trying to do two
things. One is setup a build environment where kde apps like desktoptojson
can run, the other is creating a bundle, preferably using the same
Qt. I got quite far by manually fixing up the applications built as part
of kcoreaddons and then manually patching up the executable inside the
bundle to have the @executable_path/../Frameworks rpath added. But I'm
still not sure why with a really simple example things don't work out
of the box: I guess I had better build Qt with -norpath.
