Description
After building Qt Creator from sources with CMake, I get:
$ bin/qtcreator
bin/qtcreator: error while loading shared libraries: libQt6Concurrent.t.so.6: cannot open shared object file: No such file or directory
$ ldd bin/qtcreator

This happens because the RPATH contains a nonsensical entry:
$ readelf -d bin/qtcreator | grep PATH 0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib64/qtcreator:$ORIGIN/../lib64/Qt/lib:$ORIGIN/../lib64/qtcreator/plugins]
That "/Qt/lib" is just wrong. It comes from QtCreatorAPIInternal.cmake:
file(RELATIVE_PATH _PLUGIN_TO_LIB "/${_IDE_PLUGIN_PATH}" "/${_IDE_LIBRARY_PATH}") file(RELATIVE_PATH _PLUGIN_TO_QT "/${_IDE_PLUGIN_PATH}" "/${_IDE_LIBRARY_BASE_PATH}/Qt/lib") file(RELATIVE_PATH _LIB_TO_QT "/${_IDE_LIBRARY_PATH}" "/${_IDE_LIBRARY_BASE_PATH}/Qt/lib")
That's hardcoded, instead of guessed from Qt. Since it obviously makes no sense and does not come from inspecting the Qt builds, it can't be right.
