proj was not found in the pkg-config search path

I'm getting the following error after installing on WSL. Any ideas? Thanks!

>>> go run main.go
go build github.com/twpayne/go-proj/v10:
# pkg-config --cflags  -- proj
Package proj was not found in the pkg-config search path.
Perhaps you should add the directory containing `proj.pc'
to the PKG_CONFIG_PATH environment variable
No package 'proj' found
pkg-config: exit status 1

I installed proj with sudo apt-get install proj-bin and I can run the proj command so it seems like it installed correctly.

>>> proj
Rel. 7.2.1, January 1st, 2021

You need to install the libproj-dev package.

That was it. Thanks!
