+If you want to install openrc into a custom directory such as /opt/openrc
+```shell
+$ CUSTOM_PREFIX=/opt/openrc && meson setup 
+  --prefix="$CUSTOM_PREFIX" --bindir=bin --sbindir=sbin --sysconfdir="$CUSTOM_PREFIX/etc" \
+  build
+```
+After, setting it up install openrc by this command. 
+```shell
+$ meson install --destdir='' -C build
 ```
+In our case, openrc is going to be correctly installed at /opt/openrc
