Update commit 1c15eb39d2 (Tests: Suppress failures on macOS arm64 due to
separate Xcode signing phase, 2021-02-22, v3.20.0-rc2~11^2) for Xcode 15,
which ignores our `-Xlinker -adhoc_codesign` flag, prioritizes its own
`-Xlinker -no_adhoc_codesign` flag, and does not add an ad-hoc signature
at link time.
Issue: #21845
Some tests fail because Xcode runs `POST_BUILD` commands before signing
the binaries they run. Tell the linker to perform ad-hoc codesign even
though Xcode normally tells it not to.
Other tests fail because `install_name_tool` does not revise ad-hoc
signatures without the codesign `linker-signed` flag. Add that flag
ourselves where needed by our tests.
For now these changes help our test suite pass so we can use it to cover
everything else. Both of these cases may need further investigation to
update CMake to help projects in general.
Issue: #21845, #21854
When linking to a shared library target that has version symlinks, add
an order-only dependency on the build statement that creates the links.
This ensures that the links exist for use at runtime.
Fixes: #19774
The proper way to use libraries is now through `target_link_libraries`
for things such as usage requirements, compile definitions, include
directories, etc. To facilitate this, allow `OBJECT` libraries to "link"
to other libraries.
