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.

Extract the effective linker during the computation of implicit artifacts
delivered by the compiler to the linker.
Define various variables describing the linker:
* CMAKE_<LANG>_COMPILER_LINKER
* CMAKE_<LANG>_COMPILER_LINKER_VERSION
* CMAKE_<LANG>_COMPILER_LINKER_ID
* CMAKE_<LANG>_COMPILER_LINKER_FRONTEND_VARIANT
This is complementary to feature introduced by commit 96a953b1ed
(Add options to specify linker tool, 2023-09-27).
Fixes: #17596, #18209, #25344
Offer the capability, through variable `CMAKE_LINKER_TYPE`, as well as
the target property `LINKER_TYPE` to specify which linker must be used.
The implementation of this capability is specified by variables specific
to the language and linker type: `CMAKE_<LANG>_USING_LINKER_<TYPE>`.
Some definitions are provided as part of `CMake`.
For example, to select the `LLVM` linker rather than the standard one,
the type `LLD` should be specified through the variable `CMAKE_LINKER_TYPE`.
And, on `Apple`, `Linux` and some environments on `Windows`, the variable
`CMAKE_<LANG>_USING_LINKER_LLD` has value `-fuse-ld=lld`. And for `Windows`
environments based on `MSVC`, where the linker is used directly, the tool
`lld-link.exe` will be used rather than `link.exe`.

This requires knowing when a generated header is public, which we can
model using file sets. Add policy CMP0154 to treat generated sources
as private by default in targets with file sets. Generated public
headers can be specified in public file sets.

Since commit ffc06c1239 (Teach find_(library|file|path) to get prefixes
from PATH, 2015-02-18, v3.3.0-rc1~430^2) we search in `<prefix>/include`
and `<prefix>/lib` directories for prefixes with `bin` directories in
the `PATH` environment variable. The motivation was to search the
installation prefixes of MSYS and MinGW development environments
automatically.
This behavior can search undesired prefixes that happen to be in the
`PATH` for unrelated reasons. It was reverted for non-Windows hosts
within a year by commit b30b32a493 (Drop find_(library|file|path)
prefixes from PATH on non-Windows, 2016-05-09, v3.6.0-rc1~82^2) but was
kept on Windows hosts to support its motivating use case. However,
similar problems have since been observed on Windows. For example,
commit 955d6245c1 (MSVC: Revert "Teach find_library to consider the
'libfoo.a' naming convention", 2022-11-28, v3.25.1~6^2) was primarily
due to undesired discovery of libraries in `PATH`-derived prefixes.
Since commit 5e5132e1b1 (MinGW: Search for packages in standard MSYSTEM
environment prefixes, 2023-09-11) we search MSYS and MinGW environments'
prefixes explicitly, so `PATH`-derived prefixes are no longer needed for
the original motivating use case.
Fixes: #24216
MSYS2 and similar MinGW/MSYS distributions define development
environments with a `MSYSTEM` environment variable. Each such
environment has a documented installation prefix for its packages,
often provided by a `MSYSTEM_PREFIX` environment variable.
Since commit 84a25fc263 (cmake_host_system_information: Add
MSYSTEM_PREFIX query, 2023-09-08) we can look up this prefix.
Add `$MSYSTEM_PREFIX/local` and `$MSYSTEM_PREFIX` to our system search
prefixes when targeting MinGW under `MSYSTEM` environments. This is
their equivalent to `/usr/local` and `/usr`, which we search by default
on UNIX systems.
