The libplacebo pkgconfg file has a hard requirement on vulkan if it was built with it. Since we only use our vulkan code with libplacebo, we can rely on it to check the dependency is matched when we check the libplacebo package. It it's built with vulkan support, it will require the dependency to be found. This should allow building vulkan code on platforms when libplacebo detects it (Android) and we don't (no pkg-config file). The vulkan code is used via "vulkan platform" modules that are only used by libplacebo.

So we don't rely on possibly outdated headers from a previous installation. The variables in libplacebo have been around since [^1] which is in version 3.104.0 and above. We require version 4.192. [^1]: https://github.com/haasn/libplacebo/commit/98b92cd6b47dc6ed95cc69e9bb4a51b79b44573b
