Question: Long Link Time when using coverage about cmake-scripts

Alright, it's part of the 24.04 release now.

Hi there.

I think so. I think I can extend the ability to directly load objects from shared to static libraries so that it does it without your -force_load.

I have a WIP commit in another branch (https://github.com/StableCoder/cmake-scripts/tree/static-object-coverage-test) here (b54df3b).

So with this you should be able to do like this instead:

include( code-coverage )
target_code_coverage( app-core )
target_code_coverage( app-test EXCLUDE lib/* test/* "${CMAKE_BINARY_DIR}/*" FULL_OBJECTS app-core)

# Can now do normal instead of special link
target_link_libraries(app-test PRIVATE app-core)

Can you give it a quick try and confirm it works in your environment? If it does, I'll do a bit more refinement to formalize it and add it properly.

Thanks.

The updated script works pretty well! The only thing I'm noticing is that a few objects that aren't even obliquely referenced by the test fixture are being omitted.
There's a couple classes that only work on specific hardware and so mocks are used in the tests and are only instantiated by the real application.
This could be because we're building in MinSizeRel, but I can't verify right now since the Debug executable is over 4GB and fails to launch.
At any rate, I think this is a win since build times are also improved with this technique.
