Issue: can't build tectonic rust crate (0.15.0) on windows due to error with tectonic_bridge_graphite2 v0.2.2

[LordIV4]

when calling the cargo install tectonic comand, I run into the following error:

error: failed to run custom build command for tectonic_bridge_graphite2 v0.2.2

Caused by:
process didn't exit successfully: C:\Users\{USERNAME}\AppData\Local\Temp\cargo-install4o6F51\release\build\tectonic_bridge_graphite2-d7ca28945d7ea126\build-script-build (exit code: 101)

The pkg-config command could not be found.

Most likely, you need to install a pkg-config package for your OS.

If you've already installed it, ensure the pkg-config command is one of the
directories in the PATH environment variable.

If you did not expect this build to link to a pre-installed system library,
then check documentation of the tectonic_bridge_graphite2 crate for an option to
build the library from source, or disable features or dependencies
that require pkg-config.

error: failed to compile tectonic v0.15.0, intermediate artifacts can be found at C:\Users\{USERNAME}\AppData\Local\Temp\cargo-install4o6F51.
To reuse those artifacts with a future compilation, set the environment variable CARGO_TARGET_DIR to that path.

What can I do to sucessfully install the tectonic-rust crate ?

---

I tried to use cargo vcpk and managed to sucessfully compile my tectonic git pull; but still the rust package isn't able to be installed correctely.

I also have the same problem. Any ideas on how to fix it?
