Linux build fails with "undefined reference to __glew[...]"

[T-X]

When trying to build a current sonic-pi "dev" branch on Linux / Debian Sid / amd64 arch linking seems to fail with various glew functions missing:

However libglew libraries seem to be installed:

$ dpkg -l | grep glew

For the libglew issue I seem to be able to fix it with the following change:

You may well need a more unto date elixir and Erlang. I'd try installing using the pi-install-elixir.sh script in app. Then restart your terminal and check that elixir loads from the .asdf folder in your user home folder. Also, you don't really need the imgui interface. I'd run the build-all script with parameter -n which prevents it from trying to build. EDIT I also usually install the latest cmake from snap. Some early versions can cause problems.

@rbnpi thanks for your help, building and running sonic-pi with "./linux-build-all.sh -n" worked indeed!

I would love to further help debugging the issue, but I'm a bit hesitant with updating tools user or even system wide. I was hoping that things on Debian Sid aka "unstable" would be new enough. (cmake: 3.24.2-2, elixir: 1.14.0.dfsg-2, erlang: 1:24.3.4.5+dfsg-1)

Btw. using "./linux-build-all.sh --system-libs -n" does not work for me (but I should probably file a new issue for that).

libsdl2 libsdl2-dev are the packages I believe he is referring to.
