Using libraries installed by brew with clang

[nwbreneman]

Hello,

As a new brew user on macOS (and a new macOS user), I installed libssh and libssh2 to fulfill requirements for the Python package ansible-pylibssh. The package installation failed during a clang build due to not being able to find libssh installed via brew. I was able to resolve by exporting the CFLAGS variable with the correct paths: CFLAGS=-I /opt/homebrew/include -I ext -L /opt/homebrew/lib -lssh. I'm just wondering if this is expected behavior for using such dependencies from brew or if it's considered a bug. Thanks!

Here's the clang error for reference:

Did you ever get this to work?

I don't remember if I did anything else after this to be honest. Exporting the CFLAGS environment variable before doing the install did fix it for me then. I haven't tried a fresh install since this.
