+Standard Variable Names
+~~~~~~~~~~~~~~~~~~~~~~~
+
+For a ``FindXxx.cmake`` module that takes the approach of setting
+variables (either instead of or in addition to creating imported
+targets), the following variable names should be used to keep things
+consistent between find modules.  Note that all variables start with
+``Xxx_`` to make sure they do not interfere with other find modules; the
+same consideration applies to macros, functions and imported targets.
+
+``Xxx_INCLUDE_DIRS``
+  The final set of include directories listed in one variable for use by
+  client code.  This should not be a cache entry.
+
+``Xxx_LIBRARIES``
+  The libraries to link against to use Xxx. These should include full
+  paths.  This should not be a cache entry.
+
+``Xxx_DEFINITIONS``
+  Definitions to use when compiling code that uses Xxx. This really
+  shouldn't include options such as ``-DHAS_JPEG`` that a client
+  source-code file uses to decide whether to ``#include <jpeg.h>``
+
+``Xxx_EXECUTABLE``
+  Where to find the Xxx tool.
+
+``Xxx_Yyy_EXECUTABLE``
+  Where to find the Yyy tool that comes with Xxx.
+
+``Xxx_LIBRARY_DIRS``
+  Optionally, the final set of library directories listed in one
+  variable for use by client code.  This should not be a cache entry.
+
+``Xxx_ROOT_DIR``
+  Where to find the base directory of Xxx.
+
+``Xxx_VERSION_Yy``
+  Expect Version Yy if true. Make sure at most one of these is ever true.
+
+``Xxx_WRAP_Yy``
+  If False, do not try to use the relevant CMake wrapping command.
+
+``Xxx_Yy_FOUND``
+  If False, optional Yy part of Xxx sytem is not available.
+
+``Xxx_FOUND``
+  Set to false, or undefined, if we haven't found, or don't want to use
+  Xxx.
+
+``Xxx_NOT_FOUND_MESSAGE``
+  Should be set by config-files in the case that it has set
+  ``Xxx_FOUND`` to FALSE.  The contained message will be printed by the
+  :command:`find_package` command and by
+  ``find_package_handle_standard_args()`` to inform the user about the
+  problem.
+
+``Xxx_RUNTIME_LIBRARY_DIRS``
+  Optionally, the runtime library search path for use when running an
+  executable linked to shared libraries.  The list should be used by
+  user code to create the ``PATH`` on windows or ``LD_LIBRARY_PATH`` on
+  UNIX.  This should not be a cache entry.
+
+``Xxx_VERSION``
+  The full version string of the package found, if any.  Note that many
+  existing modules provide ``Xxx_VERSION_STRING`` instead.
+
+``Xxx_VERSION_MAJOR``
+  The major version of the package found, if any.
+
+``Xxx_VERSION_MINOR``
+  The minor version of the package found, if any.
+
+``Xxx_VERSION_PATCH``
+  The patch version of the package found, if any.
+
+The following names should not usually be used in CMakeLists.txt files, but
+are typically cache variables for users to edit and control the
+behaviour of find modules (like entering the path to a library manually)
+
+``Xxx_LIBRARY``
+  The path of the Xxx library (as used with :command:`find_library`, for
+  example).
+
+``Xxx_Yy_LIBRARY``
+  The path of the Yy library that is part of the Xxx system. It may or
+  may not be required to use Xxx.
+
+``Xxx_INCLUDE_DIR``
+  Where to find headers for using the Xxx library.
+
+``Xxx_Yy_INCLUDE_DIR``
+  Where to find headers for using the Yy library of the Xxx system.
+
+To prevent users being overwhelmed with settings to configure, try to
+keep as many options as possible out of the cache, leaving at least one
+option which can be used to disable use of the module, or locate a
+not-found library (e.g. ``Xxx_ROOT_DIR``).  For the same reason, mark
+most cache options as advanced.
+
+While these are the standard variable names, you should provide
+backwards compatibility for any old names that were actually in use.
+Make sure you comment them as deprecated, so that no-one starts using
+them.
+
+
+
+A Sample Find Module
+~~~~~~~~~~~~~~~~~~~~
+
+We will describe how to create a simple find module for a library
+``Foo``.
+
+The first thing that is needed is documentation.  CMake's documentation
+system requires you to start the file with a documentation marker and
+the name of the module.  You should follow this with a simple statement
+of what the module does.
+
+.. code-block:: cmake
+
+  #.rst:
+  # FindFoo
+  # -------
+  #
+  # Finds the Foo library
+  #
+
+More description may be required for some packages.  If there are
+caveats or other details users of the module should be aware of, you can
+add further paragraphs below this.  Then you need to document what
+variables and imported targets are set by the module, such as
+
+.. code-block:: cmake
+
+  # This will define the following variables::
+  #
+  #   Foo_FOUND    - True if the system has the Foo library
+  #   Foo_VERSION  - The version of the Foo library which was found
+  #
+  # and the following imported targets::
+  #
+  #   Foo::Foo   - The Foo library
+
+If the package provides any macros, they should be listed here, but can
+be documented where they are defined.  See the `Module
+Documentation`_ section above for more details.
+
+After the documentation, leave a blank line, and then add a copyright and
+licence notice block
+
+.. code-block:: cmake
+
+  #=============================================================================

+  #  License text for the above reference.)
+
+If the module is new to CMake, you may want to provide a warning for
+projects that do not require a high enough CMake version.
+
+.. code-block:: cmake
+
+  if(CMAKE_MINIMUM_REQUIRED_VERSION VERSION_LESS 3.0.0)
+    message(AUTHOR_WARNING "Your project should require at least CMake 3.0.0 to use FindFoo.cmake")
+  endif()
+
+Now the actual libraries and so on have to be found.  The code here will
+obviously vary from module to module (dealing with that, after all, is the
+point of find modules), but there tends to be a common pattern for libraries.
+
+First, we try to use ``pkg-config`` to find the library.  Note that we
+cannot rely on this, as it may not be available, but it provides a good
+starting point.
+
+.. code-block:: cmake
+
+  find_package(PkgConfig)
+  pkg_check_modules(PC_Foo QUIET Foo)
+
+This should define some variables starting ``PC_Foo_`` that contain the
+information from the ``Foo.pc`` file.
+
+Now we need to find the libraries and include files; we use the
+information from ``pkg-config`` to provide hints to CMake about where to
+look.
+
+.. code-block:: cmake
+
+  find_path(Foo_INCLUDE_DIR
+    NAMES foo.h
+    PATHS ${PC_Foo_INCLUDE_DIRS}
+    # if you need to put #include <Foo/foo.h> in your code, add:
+    PATH_SUFFIXES Foo
+  )
+  find_library(Foo_LIBRARY
+    NAMES foo
+    PATHS ${PC_Foo_LIBRARY_DIRS}
+  )
+
+If you have a good way of getting the version (from a header file, for
+example), you can use that information to set ``Foo_VERSION`` (although
+note that find modules have traditionally used ``Foo_VERSION_STRING``,
+so you may want to set both).  Otherwise, attempt to use the information
+from ``pkg-config``
+
+.. code-block:: cmake
+
+  set(Foo_VERSION ${PC_Foo_VERSION})
+
+Now we can use :module:`FindPackageHandleStandardArgs` to do most of the
+rest of the work for us
+
+.. code-block:: cmake
+
+  include(FindPackageHandleStandardArgs)
+  find_package_handle_standard_args(Foo
+    FOUND_VAR Foo_FOUND
+    REQUIRED_VARS
+      Foo_LIBRARY
+      Foo_INCLUDE_DIR
+    VERSION_VAR Foo_VERSION
+  )
+
+This will check that the ``REQUIRED_VARS`` contain values (that do not
+end in ``-NOTFOUND``) and set ``Foo_FOUND`` appropriately.  It will also
+cache those values.  If ``Foo_VERSION`` is set, and a required version
+was passed to :command:`find_package`, it will check the requested version
+against the one in ``Foo_VERSION``.  It will also print messages as
+appropriate; note that if the package was found, it will print the
+contents of the first required variable to indicate where it was found.
+
+At this point, we have to provide a way for users of the find module to
+link to the library or libraries that were found.  There are two
+approaches, as discussed in the `Find Modules`_ section above.  The
+traditional variable approach looks like
+
+.. code-block:: cmake
+
+  if(Foo_FOUND)
+    set(Foo_LIBRARIES ${Foo_LIBRARY})
+    set(Foo_INCLUDE_DIRS ${Foo_INCLUDE_DIR})
+    set(Foo_DEFINITIONS ${PC_Foo_CFLAGS_OTHER})
+  endif()
+
+If more than one library was found, all of them should be included in
+these variables (see the `Standard Variable Names`_ section for more
+information).
+
+When providing imported targets, these should be namespaced (hence the
+``Foo::`` prefix); CMake will recognize that values passed to
+:command:`target_link_libraries` that contain ``::`` in their name are
+supposed to be imported targets (rather than just library names), and
+will produce appropriate diagnostic messages if that target does not
+exist (see policy :policy:`CMP0028`).
+
+.. code-block:: cmake
+
+  if(Foo_FOUND AND NOT TARGET Foo::Foo)
+    add_library(Foo::Foo UNKNOWN IMPORTED)
+    set_target_properties(Foo::Foo PROPERTIES
+      IMPORTED_LOCATION "${Foo_LIBRARY}"
+      INTERFACE_COMPILE_OPTIONS "${PC_Foo_CFLAGS_OTHER}"
+      INTERFACE_INCLUDE_DIRECTORIES "${Foo_INCLUDE_DIR}"
+    )
+  endif()
+
+One thing to note about this is that the ``INTERFACE_INCLUDE_DIRECTORIES`` and
+similar properties should only contain information about the target itself, and
+not any of its dependencies.  Instead, those dependencies should also be
+targets, and CMake should be told that they are dependencies of this target.
+CMake will then combine all the necessary information automatically.
+
+We should also provide some information about the package, such as where to
+download it.
+
+.. code-block:: cmake
+
+  include(FeatureSummary)
+  set_package_properties(Foo PROPERTIES
+    URL "http://www.foo.example.com/"
+    DESCRIPTION "A library for doing useful things"
+  )
+
+Most of the cache variables should be hidden in the ``ccmake`` interface unless
+the user explicitly asks to edit them.
+
+.. code-block:: cmake
+
+  mark_as_advanced(
+    Foo_INCLUDE_DIR
+    Foo_LIBRARY
+  )
+
+If this module replaces an older version, you should set compatibility variables
+to cause the least disruption possible.
+
+.. code-block:: cmake
+
+  # compatibility variables
+  set(Foo_VERSION_STRING ${Foo_VERSION})
