Restore implicit include directory extraction for adaptive relative paths (!8067) · Merge requests · CMake / CMake

Update the logic added by !3204 (merged) to account for the new try_compile work directory used for the ABI check since !7656 (merged).

Paths relative to the work directory will now have one more ../ in them, so update the test data to match.

Fixes: #24279 (closed)
Backport: release
