Instead of manually adding the libcamera library and include path to
every target that requires it, declare a dependency that groups the
headers as source, the library and the include path, and use it through
the project. This simplifies handling of the dependency.

Aha, this looks interesting!

Should the 'test_libraries' be moved to some sort of dependency too ?

Can test_libraries then depend on libcamera_dep to act in a dependency
chain?

What about putting a dependency on libcamera in the libtest as you did
below for lib_mdev_test ?

They could, yes. I think it should go on top of this series though.

> chain?

They can depend on them, but I'm not sure it can act as a chain. From a
dependency point of view, yes, but from a linking point of view if dep A
includes lib A and dep B depends on dep A, dep B will link agaisnt lib
A, but meson may not mak an application depending on lib B link against
lib A automatically. That's an expected behaviour I believe, and I think
we should thus still depend on libcamera_dep explicitly here.
