# Native BastionGuard CMake integration

RootGuard is a regular CMake subdirectory at `src/rootguard`. Do not wrap it in
`ExternalProject_Add` and do not create a staged Meson installation.

Place the contents of:

```text
src/rootguard/integration/CMakeLists.rootguard.fragment.txt
```

after the main `add_executable(BastionGuard ...)` declaration.

The module creates:

- `bastionguard-rootguard`;
- `bastionguard-rootguard-action`;
- `bastionguard-rootguard-gtk`;
- alias `BastionGuard::RootGuardUI`.

The main target links to the alias. Its public build include directory is the
parent of `src/rootguard`, allowing:

```cpp
#include "rootguard/RootGuardPage.hpp"
```

All backend, polkit, policy and selected init-system install rules are inherited
by the normal top-level `cmake --install` operation. Existing
`/etc/bastionguard/rootguard.conf` is preserved; the packaged reference is
installed as `rootguard.conf.default`.
