* m4/qt5.m4: Export moc for Qt 5 in variable MOC5. Unset temporary MOC2. * m4/qt6.m4: Export moc for Qt 6 in variable MOC6. * lang/qt/src/Makefile.am: Generate .moc5 files from .h files. Generate .moc forwarding headers in moc5 subfolder. Add moc5 subfolder to include paths for Qt 5-based qgpgme library. Ditto for Qt 6. Clean up moc5 and moc6 subfolders. * lang/qt/tests/Makefile.am: List tests and test runners for Qt 5 and Qt 6. Generate .moc5 files from .cpp files of tests. Generate .moc forwarding headers in moc5 subfolder. Generate .hmoc file from t-support.h directly in moc5 subfolder. Add moc5 subfolder to include paths for all Qt 5-based tests and runners. Ditto for Qt 6. Specify sources, LDADD and CPPFLAGS for all tests and test runners for Qt 5 and Qt 6. Clean up moc5 and moc6 subfolders. -- The output of Qt 5's moc and Qt 6's moc is incompatible. Therefore, we need to generate different .moc files for Qt 5 and Qt 6 to support co-building of the Qt 5 and Qt 6 bindings. The duplication of the listing of the tests couldn't be avoided because automake doesn't understand `the_tests5 = $(the_tests:%=%5)` and couldn't match the tests with their _SOURCES. Maybe some m4 programming would have helped, but that would have made the Makefiles even more unreadable. GnuPG-bug-id: 7205
