BinaryBuilder libGL and libGLU

I am trying to use BinaryBuilder to build bullet3 with its GUI. The project uses CMake’s FIND_PACKAGE(OpenGL), which on my Ubuntu system finds the libraries at
/usr/lib/x86_64-linux-gnu/libGL.so and /usr/lib/x86_64-linux-gnu/libGLU.so

What’s the right way to provide these dependency in BinaryBuilder? I thought I could find an example in https://github.com/JuliaGL/GLFWBuilder but apparently GLFW does not link against OpenGL (or I missed it).

Installing OpenGL dev package using Alpine Linux should help:
apk add mesa-dev

That doesn’t help much if you need to link against the library, you need the library compiled for the target
