target_link_libraries: Restore transitive out-of-dir linking (!6285) · Merge requests · CMake / CMake

Brad King requested to merge brad.king/cmake:tll-out-of-dir into master Jun 29, 2021

Refactoring in !6166 (merged) accidentally dropped the persistent lookup scope tracking across multiple items that was added by !4226 (merged). This broke a transitive out-of-dir linking case not covered by our test suite. Restore the scope tracking and add a test case.

Fixes: #22363 (closed)
Backport: release
