Attempting to build Synthpod today I ran into a number of dependencies that were required for compilation (while the instructions note that some of these are optional)
sudo apt-get install meson libglu1-mesa-dev libglew-dev libvterm-dev liblilv-dev libzita-alsa-pcmi-dev libjack-dev libxcb-icccm4-dev libxcb-xrm-dev
I'd also previously installed lv2-dev libsndfile1-dev libx11-dev libcairo2-dev jackd2 libudev-dev libevdev-dev liblo-dev libasound2-dev
This is on a Pi4 with RasPi OS/Debian 5.10.63-v7l+
