Thanks for the shasum; it allowed me to discover the problem.
There are trailing spaces in the original CMakeLists.txt, which also
appear in the patch.
When sending the patch inline, these spaces are trimmed.
(The spaces are highlighted in Magit, so I was aware of them, but I
didn't realize they would be trimmed somewhere in the email pipeline.)

I will attach the patch file separately, and also a tarred version just
in case.
So you can verify that you have the right one, here's my shasum:

Adjust CMakeLists.txt to use system-provided mmg and yaml-cpp libraries.
