Install development packages for libssh2 and openssl:
```
sudo apt install libssh2-1-del libssl-dev
```
git2go library is added as a submodule (pointing to a correct v30 release). This, in turn, contains libgit2 submodule. To ensure the submodules are cloned run:
```
git submodule update --init --recursive
```

build the static git2go library:

cd static/git2go && make install-static

ensure our git-get module uses the static git2go library instead of the one downloaded by Go modules by having the following line in go.mod:
```
replace github.com/libgit2/git2go/v30 => ./static/git2go
```
build git-get with --tags static flag:
```
go build -i --tags static
```
