This is covering a different use case where your primary compilers are
HDF5 wrappers, as is the case when using the Cray Programming
Environment. The existing code tries to query the compiler using options
only available to h5cc and friends, which doesn't work when your wrapper
is not h5cc, as is the case with the CrayPE. This change instead pulls
strings out of a test binary when testing for "is your regular compiler
an HDF5 wrapper" while the "query wrapper for options" is reserved for
the "I found the hdf5 wrappers but they're not your main compiler" mode.
Format with modern markup. Clarify that the setting of
`CMAKE_REQUIRED_DEFINITIONS` is temporary. Add a note warning
about contamination of the checks by `CMAKE_<LANG>_FLAGS`.
Issue: #16973
We only define `INTERPROCEDURAL_OPTIMIZATION` behavior for C, CXX, and
Fortran languages. Do not try to enable support for other languages.
Furthermore, each language builds with a different compiler, so check
for support by CMake and the compiler for each language independently.

SWIG fails with a redefined macro error when `-dllimport` is specified
more than once. One case where you would want to specify your own
dllimport is when using SWIG with netstandard2.0. .NET Core does not
search for shared library like Mono or .NET, so you need a fully
qualified shared library name.
The CUDA compiler automatic deprecation warnings are pure noise when
doing device linking, and should be suppressed to reduce the amount of
confusion from users.
The unified headers are preferred as of NDK r15, so use them by default
if available and provide an option to use the deprecated headers.

Fixes: #16584
Adds an option CPACK_ENABLE_FREEBSD_PKG to allow CPack to look
for FreeBSD's libpkg / pkg(8). If this is set and the libpkg
headers and library are found (which they will be, by default,
on any FreeBSD system), then add a FreeBSD pkg(8) generator.
The FreeBSD package tool pkg(8) uses tar.xz files (.txz) with two
metadata files embedded (+MANIFEST and +COMPACT_MANIFEST).
This introduces a bunch of FreeBSD-specific CPACK_FREEBSD_PACKAGE_*
variables for filling in the metadata; the Debian generator does
something similar. Documentation for the CPack CMake-script is styled
after the Debian generator.
Implementation notes:
- Checks for libpkg -- the underlying implementation for pkg(8) --
and includes FreeBSD package-generation if building CMake on
a UNIX host. Since libpkg can be used on BSDs, Linux and OSX,
this potentially adds one more packaging format. In practice,
this will only happen on FreeBSD and DragonflyBSD.
- Copy-paste from cmCPackArchiveGenerator to special-case
the metadata generation and to run around the internal
archive generation: use libpkg instead.
- Generating the metadata files is a little contrived.
- Most of the validation logic for package settings is in
CPackFreeBSD.cmake, as well as the code that tries to re-use
packaging settings that may already be set up for Debian.
- libpkg has its own notion of output filename, so we have
another contrived bit of code that munges the output file
list so that CPack can find the output.
- Stick with C++98.
The change in commit v3.8.0-rc1~60^2 (Android: Pass sysroot include
directory explicitly, 2017-01-20) does not make sense when compiling
with a standalone toolchain which is tied to a single API version.
Drop the explicit include directory so that the compiler uses its
default system include order.

The find commands already know how to search in variants of the
Program Files folders on Windows. Use PATH_SUFFIXES to tell them
under what directory within Program Files to find htmlhelp.

dcf559d0 SDCC: Do not explicitly ask linker to generate Intel Hex files

The imported targets added by commit v3.9.0-rc1~55^2 (Improve Doxygen
support, 2017-04-10) need to be guarded against duplicate creation on
multiple inclusion.
The `--out-fmt-ihx` option added by commit v2.6.0~1253 (...use
--out-fmt-ihx to enforce .ihx files, 2007-08-15) may interfere with
options requested by the user. Also, when no linker output is
specified, SDCC outputs Intel Hex by default anyway.

This modification is necessary if the GSL libraries are installed
in an installation layout without Release and Debug subdirectories,
for example when installed by vcpkg .
There are no specific options for MSVC to set language standards, but
set them as empty strings anyways so the feature test infrastructure
can at least check to see if they are defined.
Add default implementations for the cmake_record_lang_compile_features
macros. All implementations of this are the same so it can be safely
factored out to a common implementation.
