the qt build with glib results in different ldd pathes then with my own dbus


----

with own glib

export PKG_CONFIG_PATH=~/qt6_dev/glib-install/lib/x86_64-linux-gnu/pkgconfig
../qt6/qtbase/configure -debug -opensource -nomake examples -nomake
tests -prefix ~/qt6_dev/qt6-install
cmake --build . --parallel 4
cmake --install .

objdump -p ~/qt6_dev/qt6-install/lib/libQt6Core.so | grep PATH
objdump -p ~/qt6_dev/qt6-install/lib/libQt6DBus.so | grep PATH
   both return
     RUNPATH              $ORIGIN

but ldd returns different paths with lld depending on the path i am in

~/qt6_dev/qt6-build$ ldd ./lib/libQt6Core.so | grep libglib
   libglib-2.0.so.0 =>
/home/linux/qt6_dev/glib-install/lib/x86_64-linux-gnu/libglib-2.0.so.0
(0x00007fcf93fc1000)

~/qt6_dev/qt6-install$ ldd ./lib/libQt6Core.so | grep libglib
   libglib-2.0.so.0 => /lib/x86_64-linux-gnu/libglib-2.0.so.0
(0x00007fad3831d000)

~/qt6_dev/qt_tsan_tests_dev/_build_gcc$ ldd ./qt_tsan_tests | grep glib
   libglib-2.0.so.0 =>
/home/linux/qt6_dev/glib-install/lib/x86_64-linux-gnu/libglib-2.0.so.0
