Added more detailed CMake documentation.

- Also added better FindSphinx support so that we can detect the version and not  have a fatal error if it's too old.
- Added support for building latex documentation with -DBUILD_LATEX. Off by default.
- Added suppor for building man pages with -DBUILD_MAN. On by default (unless sphins is too old to support it).

+Unix (Make files)
+.................
+Generating make files on unix:
+
+.. parsed-literal::
+
+    bunzip2 -c jansson-|release|.tar.bz2 | tar xf -
+    cd jansson-|release|
+
+    mkdir build
+    cd build
+    cmake .. # or `ccmake ..` for a GUI.
+
+Then to build::
+    
     make
-    make test
+    make check
+    make install
+
+Windows (Visual Studio)
+.......................
+Creating Visual Studio project files from the command line:
+
+.. parsed-literal::
+
+    <unpack>
+    cd jansson-|release|
+
+    md build
+    cd build
+    cmake -G "Visual Studio 10" ..
+
+You will now have a *Visual Studio Solution* in your build directory.
+To run the unit tests build the ``RUN_TESTS`` project.
+
+If you prefer a GUI the ``cmake`` line in the above example can 
+be replaced with::
+
+    cmake-gui ..
+
+For command line help (including a list of available generators)
+for CMake_ simply run::
+
+    cmake
+
+To list available CMake_ settings (and what they are currently set to) 
+for the project, run::
+
+    cmake -LH ..
+
+Mac OSX (Xcode)
+...............
+If you prefer using Xcode instead of make files on OSX,
+do the following. (Use the same steps as 
+for :ref:`Unix <build-cmake-unix>`)::
+
+    ...
+    cmake -G "Xcode" ..
+
+Additional CMake settings
+.........................
+
+Shared library
+~~~~~~~~~~~~~~
+By default the CMake_ project will generate build files for building the
+static library. To build the shared version use::
+
+    ...
+    cmake -DBUILD_SHARED=1 ..
+
+Changing install directory (same as autoconf --prefix)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Just as with the autoconf_ project you can change the destination directory
+for ``make install``. The equivalent for autoconfs ``./configure --prefix`` 
+in CMake_ is::
+
+    ...
+    cmake -DCMAKE_INSTALL_PREFIX:PATH=/some/other/path ..
     make install
