Normally, the build system (QMake I suppose?) should take care of it.

In GNU configure parlance, if you do:

  ./configure --libdir=3D/some/thing/lib

then the build system will ensure that executables, once installed, have
/some/thing/lib in their RUNPATH.

IOW, instead of adding a post-install phase that moves files around,
make sure to pass the right libdir option to QMake or whatever.

HTH!
