CheckCXXSourceCompiles
----------------------

Check if given C++ source compiles and links into an executable.

.. command:: check_cxx_source_compiles

::

check_cxx_source_compiles(code resultVar [FAIL_REGEX regex1 [regex2...]])

Check that the source supplied in ``code`` can be compiled as a C++ source
file and linked as an executable (so it must contain at least a ``main()``
function). The result will be stored in the internal cache variable specified
by ``resultVar``, with a boolean true value for success and boolean false for
failure. If ``FAIL_REGEX`` is provided, then failure is determined by
checking if anything in the output matches any of the specified regular
expressions.

The underlying check is performed by the :command:`try_compile` command. The
compile and link commands can be influenced by setting any of the following
variables prior to calling ``check_cxx_source_compiles()``:

``CMAKE_REQUIRED_FLAGS``
Additional flags to pass to the compiler. Note that the contents of
:variable:`CMAKE_CXX_FLAGS <CMAKE_<LANG>_FLAGS>` and its associated
configuration-specific variable are automatically added to the compiler
command before the contents of ``CMAKE_REQUIRED_FLAGS``.

``CMAKE_REQUIRED_DEFINITIONS``
A :ref:`;-list <CMake Language Lists>` of compiler definitions of the form
``-DFOO`` or ``-DFOO=bar``. A definition for the name specified by
``resultVar`` will also be added automatically.

``CMAKE_REQUIRED_INCLUDES``
A :ref:`;-list <CMake Language Lists>` of header search paths to pass to
the compiler. These will be the only header search paths used by
``try_compile()``, i.e. the contents of the :prop_dir:`INCLUDE_DIRECTORIES`
directory property will be ignored.

``CMAKE_REQUIRED_LIBRARIES``
A :ref:`;-list <CMake Language Lists>` of libraries to add to the link
command. These can be the name of system libraries or they can be
:ref:`Imported Targets <Imported Targets>` (see :command:`try_compile` for
further details).

``CMAKE_REQUIRED_QUIET``
If this variable evaluates to a boolean true value, all status messages
associated with the check will be suppressed.

The check is only performed once, with the result cached in the variable
named by ``resultVar``. Every subsequent CMake run will re-use this cached
value rather than performing the check again, even if the ``code`` changes.
In order to force the check to be re-evaluated, the variable named by
``resultVar`` must be manually removed from the cache.

Если я обновлю try_compile Команда в модуле, как показано ниже, я могу проверить возможности C ++ с armcc без ошибок.
