Perhaps not the same: cmake as discribed in dev-section and of course all the libs.
Make gives this:
plugins/channelrx/demodfreedv/CMakeFiles/demodfreedv.dir/build.make:121: recipe for target 'plugins/channelrx/demodfreedv/CMakeFiles/demodfreedv.dir/freedvdemodsink.cpp.o' failed
make[2]: *** [plugins/channelrx/demodfreedv/CMakeFiles/demodfreedv.dir/freedvdemodsink.cpp.o] Error 1
CMakeFiles/Makefile2:4876: recipe for target 'plugins/channelrx/demodfreedv/CMakeFiles/demodfreedv.dir/all' failed
make[1]: *** [plugins/channelrx/demodfreedv/CMakeFiles/demodfreedv.dir/all] Error 2
Makefile:171: recipe for target 'all' failed
make: *** [all] Error 2

Is there someone who is willing to look at these errors?
Thnx!

By the way: compiling under Lubuntu (DragonOS LTS)

Title changed to reflect that actually OpenCV should not be required as modatv is the only plugin using it and is already optional.

Implemented in v4.14.4 and v5.4.0
