The change allows to selectively disable PrecompiledHeaders.
Despite the `$(VCTargetsPath)/1033/cl.xml` contains an empty value for switch,
for effectively turn off setting need to use /Y- option as described on msdn:
https://msdn.microsoft.com/en-us/library/1hy7a92h.aspx
Optional spaces and/or tabs are now understood between the '#' character
and the 'cmakedefine'/'cmakedefine01' words. This indentation is
preserved in the output lines.
Fixes: #13037
When encountering an #include "FOO.moc" statement where
FOO.hpp was chosen over FOO.cpp as the moc source, the
FOO.hpp name was not checked against the moc SKIP list.
Although `$(VCTargetsPath)/1033/link.xml` for v140 and v141 toolsets
contains an entry for `LinkControlFlowGuard`, it does not work when used
in a `.vcxproj` file. Drop our link flag table entries for these
toolsets so that the flag will be passed via `AdditionalOptions`.
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.
When `<LANG>_STANDARD` is not set we will not add any language standard
flags. If `<LANG>_EXTENSIONS` is not OFF then our default is supposed
to be ON. In order to support compilers that do not enable their
extensions by default, check a `CMAKE_<LANG>_EXTENSION_COMPILE_OPTION`
variable for an extensions flag to use without any language standard.
