+CMakePushCheckState
+-------------------
+
+
+
+This module defines three macros: ``CMAKE_PUSH_CHECK_STATE()``
+``CMAKE_POP_CHECK_STATE()`` and ``CMAKE_RESET_CHECK_STATE()`` These macros can
+be used to save, restore and reset (i.e., clear contents) the state of
+the variables ``CMAKE_REQUIRED_FLAGS``, ``CMAKE_REQUIRED_DEFINITIONS``,
+``CMAKE_REQUIRED_LINK_OPTIONS``, ``CMAKE_REQUIRED_LIBRARIES``,
+``CMAKE_REQUIRED_INCLUDES`` and ``CMAKE_EXTRA_INCLUDE_FILES`` used by the
+various Check-files coming with CMake, like e.g. ``check_function_exists()``
+etc.
+The variable contents are pushed on a stack, pushing multiple times is
+supported.  This is useful e.g.  when executing such tests in a Find-module,
+where they have to be set, but after the Find-module has been executed they
+should have the same value as they had before.
+
+``CMAKE_PUSH_CHECK_STATE()`` macro receives optional argument ``RESET``.
+Whether it's specified, ``CMAKE_PUSH_CHECK_STATE()`` will set all
+``CMAKE_REQUIRED_*`` variables to empty values, same as
+``CMAKE_RESET_CHECK_STATE()`` call will do.
+
+Usage:
+
+.. code-block:: cmake
+
+   cmake_push_check_state(RESET)
+   set(CMAKE_REQUIRED_DEFINITIONS -DSOME_MORE_DEF)
+   check_function_exists(...)
+   cmake_reset_check_state()
+   set(CMAKE_REQUIRED_DEFINITIONS -DANOTHER_DEF)
+   check_function_exists(...)
+   cmake_pop_check_state()
