+To skip bundled (`third-party/*`) dependencies:
+
+1. Install the dependencies using a package manager.
+   ```
+   sudo apt install gperf luajit luarocks libuv1-dev libluajit-5.1-dev libunibilium-dev libmsgpack-dev libtermkey-dev libvterm-dev

+   make CMAKE_BUILD_TYPE=RelWithDebInfo USE_BUNDLED=OFF
+   sudo make install
+   ```
+
+To inspect the build, these CMake features are useful:
 
 - `cmake --build build --target help` lists all build targets.
 - `build/CMakeCache.txt` (or `cmake -LAH build/`) contains the resolved values of all CMake variables.
 - `build/compile_commands.json` shows the full compiler invocations for each translation unit.
