This will install the `hx` binary to `$HOME/.cargo/bin` and build tree-sitter grammars in `./runtime/grammars`.
If you are using the musl-libc instead of glibc the following environment variable must be set during the build
to ensure tree sitter grammars can be loaded correctly:
```
RUSTFLAGS="-C target-feature=-crt-static"
```
Helix also needs its runtime files so make sure to copy/symlink the `runtime/` directory into the
config directory (for example `~/.config/helix/runtime` on Linux/macOS). This location can be overridden
via the `HELIX_RUNTIME` environment variable.
