[Possible regression 6.4.x->6.5.0] Cannot add translation to project from subdirectory (CMake)

Please find the attached reproducer and run it on Qt6.5.0.

Trying to add translation from CMakeLists.txt in subdirectory 'translations': CMake cannot find source file xxx.qm.
Trying to add translation from CMakeLists.txt in root (parent) subdirectory: works fine.

However, adding translation from subdirectory works in Qt6.4.x.

The issue seems to influence many other CMake commands that involves 'target', e.g., add shader or add resource.
