libegl not looked for by cmake

I'm trying to build maim from source. cmake succeeded, but then make failed with this:

Shouldn't cmake have told me I was missing a dependency? Also, in the README.md's advice about installing dependencies first, shouldn't there be a mention of libegl?

Is there a workaround? I have libegl1-mesa installed but still get the make error.

It looks like libegl1-mesa-dev works.
