This is because cmake has its own incompatible mechanism to tell users about compilation and linking flags, and the "dependency" line doesn't tell Meson if u2f-emu has a pkg-config or a cmake description. We can ask to use pkg-config only since none of our dependencies are cmake-only; see https://mesonbuild.com/Dependencies.html#dependency-method.

Why is Meson trying to use CMak= e here? I don't think we want
to bring in another build tool dependency...

It's asking cmake if it kno= ws about the package, if pkg-config fails. This is because cmake has its ow= n incompatible mechanism to tell users about compilation and linking flags,= and the "dependency" line doesn't tell Meson if u2f-emu has = a pkg-config or a cmake description.

We can ask to use pkg-config only since none of our dependenci= es are cmake-only; see https://mesonbuild.com/Dependencies.html#dependency-meth= od.
