This is not directly related but I once spent some time trying to satisfy pkg-config dependencies on Windows. This is what I ended up with: https://github.com/input-output-hk/cardano-node/blob/8bb0d2322d81bb9e73553f5823af7d307910369d/doc/getting-started/building-the-node-on-windows.md

In particular you can install pkg-config with `choco install pgkconfiglite` using chocolatey package manager.

I understand this error message as: You need to install pkg-config first.
pkg-config is the tool that manages path and versions of installed C
libraries and Cabal uses it to query existence and compiler flags of
installed C libraries.

On Windows I used MSYS2 and this helped a lot to install components like
pkg-config and other C libraries plus their interfaces._______________________________________________
