compile issues with nightly build

[chilina]

From forum thread here: https://forum.openframeworks.cc/t/tesselator-h-and-compiling-the-rpi-nightly-build/43856

With of_v20240901_linuxarmv6l_release, compiling with the compileOF.sh script fails with: ../../../libs/openFrameworks/utils/ofConstants.h:306:10: fatal error: tesselator.h: No such file or directory 306 | #include <tesselator.h> | ^~~~~~~~~~~~~~ compilation terminated.

Trying to compile on an RPi3B with 32-bit Bullseye, following the setup guide (which is very nicely written now and I'm finding it very easy to follow).

@dimitre thinks that maybe the libs path isn't getting included in the makefile.
