I'm trying to build this in gitaly-git2go branch,

https://salsa.debian.org/go-team/packages/gitaly/-/tree/gitaly-git2go

gopkg.in/libgit2/git2go.v28
# pkg-config --cflags --static -- 
/<<PKGBUILDDIR>>/obj-x86_64-linux-gnu/src/gopkg.in/libgit2/git2go.v28/static-build/install/lib/pkgconfig/libgit2.pc

pkg-config: exit status 1

This is a bug in golang-gopkg-libgit2-git2go.v28-dev

We will have to patch this to look for libgit2.pc from system
