Revert commit 502610733f (Ensure imported targets in sibling dirs are
deduplicated, 2024-09-15, v3.31.0-rc1~92^2). Also revert the change
from a copy of the logic made by commit cd418d4bb6 (Static libraries
de-duplication: keep first occurrence, 2024-09-29, v3.31.0-rc1~30^2).
The logic was de-duplicating based on the target name rather than based
on the library file path.
Fixes: #26371
Issue: #26284
In `Tests/RunCMake/LinkerSelection`, Xcode 16 warns when building the
AppleClassic case:
ld: warning: -ld_classic is deprecated and will be removed
in a future release
Tolerate all build warnings.
Some platforms, Apple or Windows for instance, do not require to duplicate
static libraries to resolve mutual dependencies. Moreover, Xcode version 15
emits a warning if a library is duplicated.
On Windows, enable a better control of libraries order.
Fixes: #20722, #25297
