Set the variable added by commit a2112257 (Add infrastructure to use
language extensions without any standard, 2017-06-29) for IAR. This was
accidentally left out of commit d8e6cd9e (IAR: Improve support for IAR
ARM Compiler, 2017-06-15).
Currently the implementation macro for `check_symbol_exists` is
`_check_symbol_exists`, which impedes CMake users from overriding the
`check_symbol_exists` macro themselves.
- Added clearer structure by grouping the options into logical sections.
- Expanded the details for many of the options.
- Added Examples section to show how to use the various commands.
- Specifically highlighted that the contents of SOURCE_DIR may be lost
if a download method is also provided.
- Updated argument-matching regex to be more robust and account for the
varying leading spaces before keywords in the docs.
- Updated tests to account for slightly changed error messages.
Visual Studio 2015 Update 3 introduced the notion of language standard
levels to MSVC. The language standard level is defined in `_MSVC_LANG`
instead of `__cplusplus`. It also added support for the `-std:c++14`
and `-std:c++latest` flags, although the compiler defaults to its C++14
mode anyway. Visual Studio 2017 Update 3 will introduce support for the
`-std:c++17` flag.

* LIBXML2_INCLUDE_DIR talks about libxml2 itself;
* LIBXML2_INCLUDE_DIRS lists also include directories coming from
libxml2's dependencies and is what libxml2 users should use;
* LIBXML2_LIBRARY talks about libxml2 itself;
* LIBXML2_LIBRARIES is what libxml2 users should link to.
This commit doesn't break existing users of FindLibXml2.cmake,
but provides the way for correct behaviour in future. In particular,
on OpenBSD LIBXML2_INCLUDE_DIR resolves to /usr/local/include/libxml2,
while libiconv (an libxml2 dependency) puts iconv.h
in /usr/local/include, which is not picked up automatically.
The logic added in commit v3.6.0-rc1~30^2 (Add a variable to specify
language-wide system include directories, 2016-05-24) to use
`CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES` incorrectly filters them by
`CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`. Rather than recognizing
this, commit v3.8.0-rc1~60^2 (Android: Pass sysroot include directory
explicitly, 2017-01-20) worked around the problem by incorrectly
removing `/usr/include` from `CMAKE_<LANG>_IMPLICIT_INCLUDE_DIRECTORIES`
so it worked in `CMAKE_<LANG>_STANDARD_INCLUDE_DIRECTORIES`.
By not filtering out `/usr/include` from user-specified include
directories, we allow the code
include_directories(${CMAKE_SYSROOT}/usr/include)
to place the include directory too early on the command line.
Fix support for standard include directories to not be filtered by
implicit include directories, and do not remove `/usr/include` from the
list of implicit include directories for Android builds. Add a test
case to verify that an explicit `/usr/include` is ignored in favor
of the standard directory at the end.

This option was added by commit v2.8.12~138^2 (Add
cmake_reset_check_state() macro, 2013-07-28) but has never worked.
Fix the implementation to refer to macro arguments properly (not as
normal variables).

Since commit v3.8.0-rc1~47^2 (FindPkgConfig: Recheck pkg-config on
parameter change, 2017-01-17) calling `pkg_check_modules` always
re-runs. The problem is that if there are only 2 arguments passed to
`pkg_check_modules```, then `_module0` will be set and `ARGN` will be
empty. When this is written to cache it will be stored as just the
value of `_module0` without any semicolon, so on the next run this
doesn't match the expected value and the search is rerun.
Revise the logic to handle the case of empty `ARGN` separately.
Fixes: #17003
When searching for shared libraries on Windows, add
H5_BUILT_AS_DYNAMIC_LIB to HDF5_DEFINITIONS so that the header file
knows how to dllimport the symbols.

FindDoxygen generates some files based on the version of Doxygen whose
content will not vary across a project and are therefore a global
resource that can be shared by all calls to `find_package(Doxygen)` and
to `doxygen_add_docs`. We currently use `${PROJECT_BINARY_DIR}` to
reference their location, but this is not stable because `project()`
calls in a subdirectory can change it. Use `${CMAKE_BINARY_DIR}`
instead.

Make the implementation for this compiler more complete.
IAR has multiple C++ modes, historically they were reduced c++ versions
for embedded that gradually improved to the full standard (which can be
reduced again by e.g. disabling rtti and exceptions). The new
implementation picks the best available, but the c++ mode can also be
overridden by defining `CMAKE_IAR_CXX_FLAG`.
Add C/C++ standard flags so that all modes up to and including the last
supported standard are defined.
Fixes: #16826
Compilers such as MSVC and IAR may have variants that target different
architectures. We have been using a `MSVC_<LANG>_ARCHITECTURE_ID`
variable to hold this information for MSVC. Add an alternative with a
more general name (later we can port MSVC to it too).
This additional information may be needed to generate proper invocations
of the compiler based on its architecture variant.

While some features require external Unix tools the
generator is mostly portable.
By enabling it on Windows it can be used for cross platform
packaging.
