I compile the project on a Mac and I did the set up of the development environment accordingly to your instructions as described in the read.me. The "hello world" app is running without errors. After "make app" of the esp-32 cam app I get this errors:

That issue was recently fixed. Pull the latest commit for this repo and the esp32-camera sub module repo.

See also Issue #3. If you get it working on a Mac it would be useful to add a Mac section to the docs.

I got it working on the mac! The problem was, that I followed the link posted in your readme file to set up the esp-idf environment. The posted link links you to the stable version v3.3.1 of ESP-IDF, but you ask to use v4.0 of ESP-IDF. Probably you update the link in your read me file.

You did a great job, it works perfect!
