Compile error with CLAP on RPi

Trying to compile on Raspberry Pi 4, and cmake fails with:

Don't want CLAP part, rather have a LV2 plugging for Carla, and maybe a standalone. Not sure how to pass options to cmake for that.

It's not CLAP.

You are missing the git submodule.

You should have run git submodule update --init at least

Sorry git submodule update --init --recursive otherwise it's only half the job.
