- Use CFLAGS and CXXFLAGS instead of CMAKE_CXX_FLAGS and CMAKE_C_FLAGS.
- Use MODCMAKE_LDFLAGS instead of CMAKE_EXE_LINKER_FLAGS
- Fix broken builds with CMake 3.23
- remove gmic-qt/krita (broken)
- set quirk to replace it with krita-gmic-plugin
- set EPOCH in krita-gmic-plugin because 3.0.0.2 > 3.0.2
- set conflict marker in krita-gmic-plugin
With help from radowski@, sthen@
OK sthen@
mark gmic-qt-krita as broken, because krita decided to fork their
own copy of gmic, which obviously isn't currently built, as our
fearless porters didn't notice.
enable gmic-qt-none, a stand-alone version of gmic-qt that may be now
used in batch-mode by software like blender
