I don’t quite understand why `find_library` fails locate a framework when cross-compiling for tvOS:

```auto

The library is bundled in a framework and available at `/Users/developer/Documents/Qt-build/install/lib/libavdevice.framework/libavdevice`. But this path was not even considered, as you can see from the output above.

At the same time `find_path` has no problem with it:

```auto

```

Is there a configuration variable or `find_library` setting that may prevent it from looking for frameworks?

`CMAKE_FIND_FRAMEWORK` is probably what you’re looking for. It’s not all that common to see anything set that though.

`find_library` can properly locate frameworks. It’s just output of --debug-find fails to mention framework locations. See [https://gitlab.kitware.com/cmake/cmake/-/issues/25547](https://gitlab.kitware.com/cmake/cmake/-/issues/25547)
