Organize pages into directories and shorter file names.  Use lower-case
names for directories and capitalized names for files.  This produces a
pleasing sort order in the GitLab Wiki navigation page.

Also rename entry page `CMake.md` to `Home.md` to match GitLab Wiki
conventions.

+# Generating Dependency Graphs with CMake
+
+By using CMake you can automatically generate dependency graphs
+(dot/graphviz) of the targets in your project. This works for
+dependencies within the project, as well as dependencies to external
+libraries.
+
+## Usage
+
+To use it, run cmake in the build tree:
+
+cmake --graphviz=test.dot .
+
+## Customize graphviz output
+
+The output can be customized with the following options in
+CMakeGraphVizOptions.cmake (located in base source directory)
+
+### graphviz options
+
+  - GRAPHVIZ_GRAPH_TYPE - default: 'digraph'
+  - GRAPHVIZ_GRAPH_NAME - default: 'GG'
+  - GRAPHVIZ_GRAPH_HEADER - default: 'node \[\\n fontsize =
+    \\"12\\"\\n\];'
+  - GRAPHVIZ_NODE_PREFIX - default: 'node'
+
+### module inclusion config
+
+  - GRAPHVIZ_EXECUTABLES - Export executables (default: ON)
+  - GRAPHVIZ_STATIC_LIBS - Export static libs (default: ON)
+  - GRAPHVIZ_SHARED_LIBS - Export shared libs (default: ON)
+  - GRAPHVIZ_MODULE_LIBS - Export modules (default: ON)
+  - GRAPHVIZ_EXTERNAL_LIBS - Export external libs (default: ON)
+  - GRAPHVIZ_IGNORE_TARGETS - Do not export targets in the given list.
+    Since 2.8.5 this supports regular expressions.
+  - GRAPHVIZ_IGNORE_TARGETS_REGEX - Do not export targets which match
+    the given regex. Not supported anymore since 2.8.5.
