At first glance, those might work, but when I go to the README, there's no mention of those binaries, and it links to the wiki under "Build and Install".
However going to the project website at https://webcamoid.github.io/ it does link to the executables, which is a little clearer.
I guess I've gotten used to going to the Github repo for projects more than most would.
