Help: Factor out find_* command duplication

These documents were represented in the builtin documentation using a
common starting point with placeholders substituted by each command.
Convert them back to this approach using the reStructuredText include
directive and substitutions to avoid duplication.

+A short-hand signature is:
+
+.. parsed-literal::
+
+   |FIND_XXX| (<VAR> name1 [path1 path2 ...])
+
+The general signature is:
+
+.. parsed-literal::
+
+   |FIND_XXX| (
+             <VAR>
+             name | |NAMES|
+             [HINTS path1 [path2 ... ENV var]]
+             [PATHS path1 [path2 ... ENV var]]
+             [PATH_SUFFIXES suffix1 [suffix2 ...]]
+             [DOC "cache documentation string"]
+             [NO_DEFAULT_PATH]
+             [NO_CMAKE_ENVIRONMENT_PATH]

+              NO_CMAKE_FIND_ROOT_PATH]
+            )
+
+This command is used to find a |SEARCH_XXX_DESC|.
+A cache entry named by ``<VAR>`` is created to store the result
+of this command.
+If the |SEARCH_XXX| is found the result is stored in the variable
+and the search will not be repeated unless the variable is cleared.
+If nothing is found, the result will be
+``<VAR>-NOTFOUND``, and the search will be attempted again the
+next time |FIND_XXX| is invoked with the same variable.
+The name of the |SEARCH_XXX| that
+is searched for is specified by the names listed
+after the NAMES argument.   Additional search locations
+can be specified after the PATHS argument.  If ENV var is
+found in the HINTS or PATHS section the environment variable var
+will be read and converted from a system environment variable to
+a cmake style list of paths.  For example ENV PATH would be a way
+to list the system path variable. The argument
+after DOC will be used for the documentation string in
+the cache.
+PATH_SUFFIXES specifies additional subdirectories to check below
+each search path.
+
+If NO_DEFAULT_PATH is specified, then no additional paths are
+added to the search.
+If NO_DEFAULT_PATH is not specified, the search process is as follows:
+
+.. |CMAKE_PREFIX_PATH_XXX_SUBDIR| replace::
+   <prefix>/|XXX_SUBDIR| for each <prefix> in CMAKE_PREFIX_PATH
+
+.. |CMAKE_SYSTEM_PREFIX_PATH_XXX_SUBDIR| replace::
+   <prefix>/|XXX_SUBDIR| for each <prefix> in CMAKE_SYSTEM_PREFIX_PATH
+
+1. Search paths specified in cmake-specific cache variables.
+   These are intended to be used on the command line with a -DVAR=value.
+   This can be skipped if NO_CMAKE_PATH is passed.
+
+   * |CMAKE_PREFIX_PATH_XXX|
+   * |CMAKE_XXX_PATH|
+   * |CMAKE_XXX_MAC_PATH|
+
+2. Search paths specified in cmake-specific environment variables.
+   These are intended to be set in the user's shell configuration.
+   This can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.
+
+   * |CMAKE_PREFIX_PATH_XXX|
+   * |CMAKE_XXX_PATH|
+   * |CMAKE_XXX_MAC_PATH|
+
+3. Search the paths specified by the HINTS option.
+   These should be paths computed by system introspection, such as a
+   hint provided by the location of another item already found.
+   Hard-coded guesses should be specified with the PATHS option.
+
+4. Search the standard system environment variables.
+   This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.
+
+   * |SYSTEM_ENVIRONMENT_PATH_XXX|
+
+5. Search cmake variables defined in the Platform files
+   for the current system.  This can be skipped if NO_CMAKE_SYSTEM_PATH
+   is passed.
+
+   * |CMAKE_SYSTEM_PREFIX_PATH_XXX|
+   * |CMAKE_SYSTEM_XXX_PATH|
+   * |CMAKE_SYSTEM_XXX_MAC_PATH|
+

+   These are typically hard-coded guesses.

 find_path
 ---------
 
-Find the directory containing a file.
-
-::
-
-   find_path(<VAR> name1 [path1 path2 ...])
-
-This is the short-hand signature for the command that is sufficient in
-many cases.  It is the same as find_path(<VAR> name1 [PATHS path1
-path2 ...])
-
-::
-
-   find_path(
-             <VAR>
-             name | NAMES name1 [name2 ...]
-             [HINTS path1 [path2 ... ENV var]]

-This command is used to find a directory containing the named file.  A
-cache entry named by <VAR> is created to store the result of this
-command.  If the file in a directory is found the result is stored in
-the variable and the search will not be repeated unless the variable
-is cleared.  If nothing is found, the result will be <VAR>-NOTFOUND,
-and the search will be attempted again the next time find_path is
-invoked with the same variable.  The name of the file in a directory
-that is searched for is specified by the names listed after the NAMES
-argument.  Additional search locations can be specified after the
-PATHS argument.  If ENV var is found in the HINTS or PATHS section the
-environment variable var will be read and converted from a system
-environment variable to a cmake style list of paths.  For example ENV
-PATH would be a way to list the system path variable.  The argument
-after DOC will be used for the documentation string in the cache.
-PATH_SUFFIXES specifies additional subdirectories to check below each
-search path.
-
-If NO_DEFAULT_PATH is specified, then no additional paths are added to
-the search.  If NO_DEFAULT_PATH is not specified, the search process
-is as follows:
-
-1.  Search paths specified in cmake-specific cache variables.  These
-are intended to be used on the command line with a -DVAR=value.  This
-can be skipped if NO_CMAKE_PATH is passed.

-On Darwin or systems supporting OS X Frameworks, the cmake variable
-CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:
-
-::
-
-   "FIRST"  - Try to find frameworks before standard

-   "LAST"   - Try to find frameworks after standard
-              libraries or headers.
-   "ONLY"   - Only try to find frameworks.
-   "NEVER" - Never try to find frameworks.
-
-On Darwin or systems supporting OS X Application Bundles, the cmake
-variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the
-following:
-
-::
-
-   "FIRST"  - Try to find application bundles before standard
-              programs. This is the default on Darwin.

-              programs.
-   "ONLY"   - Only try to find application bundles.
-   "NEVER" - Never try to find application bundles.
-
-The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
-directories to be prepended to all other search directories.  This
-effectively "re-roots" the entire search under given locations.  By
-default it is empty.  It is especially useful when cross-compiling to
-point to the root directory of the target environment and CMake will
-search there too.  By default at first the directories listed in
-CMAKE_FIND_ROOT_PATH and then the non-rooted directories will be
-searched.  The default behavior can be adjusted by setting
-CMAKE_FIND_ROOT_PATH_MODE_INCLUDE.  This behavior can be manually
-overridden on a per-call basis.  By using CMAKE_FIND_ROOT_PATH_BOTH
-the search order will be as described above.  If
-NO_CMAKE_FIND_ROOT_PATH is used then CMAKE_FIND_ROOT_PATH will not be
-used.  If ONLY_CMAKE_FIND_ROOT_PATH is used then only the re-rooted
-directories will be searched.

 the framework search will look for A.framework/Headers/b.h.  If that
