+### Statically linking with musl library
+
+The process requires you to have `musl-gcc` in your `$PATH` environment variable.
+For installing musl library see this [page](https://www.musl-libc.org/how.html)
+The `static` flag is used for linking statically.
+
+```bash
+export CC="musl-gcc -static -Os"
+mkdir -p build && cd build
+cmake ../
+make -j<number of cores>
+
+```
