fatal: not a git repository (or any of the parent directories): .git

When trying to compile a project which uses

boring = { version = "2.1.0", features = ["fips"], optional = true }

I hit the following error:

The following warnings were emitted during compilation:

warning: fetching boringssl git submodule

error: failed to run custom build command for `boring-sys v2.1.0`
note: To improve backtraces for build dependencies, set the CARGO_PROFILE_TEST_BUILD_OVERRIDE_DEBUG=true environment variable to enable debug information generation.
