CMAKE_FIND_LIBRARY_PREFIXES and CMAKE_FIND_LIBRARY_SUFFIXES have
different behavior when undefined and when defined but empty:
Empty means to use an empty prefix/suffix while undefined means to
use a hardcoded default for the platform we are running on.
Unfortunately, set(a ${b}) will undefine a when b is empty,
meaning that when targeting a platform where either of these variables
is empty (e.g. Windows where CMAKE_FIND_LIBRARY_PREFIXES is empty)
the unpatched FindZLIB code ends up unsetting that variable, causing
all subsequent find_library calls to use the hardcoded default
for the runtime platform (e.g. "lib" for CMAKE_FIND_LIBRARY_PREFIXES
on Linux).
On the other hand, set(a "${b}") will always define a to be empty but
defined so we have to do this dance to fully preserve the state of these
variables.
`CMakeFindBinUtils.cmake` sets `CMAKE_<TOOL>` variables that in
cross-compilation environments point to the toolchain specific
executables: e.g. `CMAKE_OBJCOPY` might point to
`<path_to_toolchain>/arm-poky-linux-gnueabi-objcopy`.
Pass this information to CPack.
This approach is compatible with both Intel and Apple Silicon
architectures.
`/usr/local/Frameworks` was added in commit 9970cdcb59
(CMakeFindFrameworks: Allow custom framework locations, 2016-07-30,
v3.7.0-rc1~296^2) unconditionally, but does not work on Apple Silicon.
```
x86_64 (Intel macOS):
$ brew --prefix
/usr/local
arm64 (Apple Silicon macOS):
$ brew --prefix

```
this last resort check is for some HPC with "module load matlab"
not enacted that fail to catch in earlier checks. That would
error CMake configure even if find_package(Matlab) is not REQUIRED

Extend the change from commit 4153d8445b (Add CMAKE_CTEST_ARGUMENTS
variable to pass command-line arguments to ctest, 2019-12-28,
v3.17.0-rc1~150^2) to cover the test target alias created by
`CTEST_TEST_TARGET_ALIAS` too.
This should allow:
set(CMAKE_CTEST_ARGUMENTS -T Test --no-compress-output)
set(CTEST_TEST_TARGET_ALIAS runtests)
include(CTest)
to use the arguments as part of `make runtests`.

Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_80_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.80.0 source tree.
They are the same as 1.79's dependencies, so just update
the version check for warning about newer versions.

`find_package(Vulkan REQUIRED FATAL_ERROR)` calls exist in the wild, but
`find_package` does not have a `FATAL_ERROR` option. We silently
tolerated such calls prior to commit 6e4d20921d (FindVulkan: Add
component for `shaderc_combined`, 2022-05-18, v3.24.0-rc1~111^2~5), by
treating the argument as a component and ignoring it. Restore tolerance
by removing the component and warning about it.

Instead of printing the output of the last attempt, print
the output of all attempts. This shows users that CMake isn't ignoring any provided flags ( LANG_FLAGS ).
