I use an alpine container to run my CI.
I get an error that says I am missing assert.h when building a c dependency. I don’t know where im leaking into system installed headers… as far as I know I am not linking system libraries for this build.
here is the build log:

Where in my dependency is it trying to pull in system headers?
