Joerg Bornemann 5430fb2243 CMake: Set RPATH of deployed plugins on Linux
When deploying into some directory structure where CMAKE_INSTALL_LIBDIR
is different from Qt's lib dir, we need to set the RPATH of installed
plugins such that Qt libraries are found.

We do this using CMake's undocumented file(RPATH_SET) command and pray
that this command is safe to use across current and future CMake
versions.  For CMake versions < 3.21, we use patchelf, which must be
installed on the host system.

The adjustment of rpaths can be turned on explicitly by setting
QT_DEPLOY_FORCE_ADJUST_RPATHS to ON.

The usage of patchelf can be forced by setting QT_DEPLOY_USE_PATCHELF to
ON regardless of the CMake version.
