JACK Error building headless on Raspberry Pi

[tedmoore]

Environment

• SuperCollider version: 13.13.0 (haven't successfully built yet)
• Operating system:

PRETTY_NAME="Debian GNU/Linux 12 (bookworm)"
NAME="Debian GNU/Linux"
VERSION_ID="12"
VERSION="12 (bookworm)"

Steps to reproduce

I'm following the install Installation instructions in this repos README_RASPBERRY_PI.md. I am trying to build headless and am SSHing into the Raspberry Pi. I have installed jack2 per the previous instructions in the document.

When I get to the step to run cmake -DCMAKE_BUILD_TYPE=Release -DSUPERNOVA=OFF -DSC_ED=OFF -DSC_EL=OFF -DSC_VIM=ON -DNATIVE=ON -DSC_IDE=OFF -DNO_X11=ON -DSC_QT=OFF .. I get this error:

-- Checking for module 'jack'
--   Package 'jack', required by 'virtual:world', not found
CMake Error at /usr/share/cmake-3.25/Modules/FindPkgConfig.cmake:607 (message):

  /usr/share/cmake-3.25/Modules/FindPkgConfig.cmake:829 (_pkg_check_modules_internal)
  server/scsynth/CMakeLists.txt:47 (pkg_check_modules)

The instructions install jack2 and cmake is looking for jack is this the problem.
