VS_GLOBAL_SECTION_POST_<section>
--------------------------------

Specify a postSolution global section in Visual Studio.

Setting a property like this generates an entry of the following form
in the solution file:

::

  GlobalSection(<section>) = postSolution
    <contents based on property value>
  EndGlobalSection

The property must be set to a semicolon-separated list of key=value
pairs.  Each such pair will be transformed into an entry in the
solution global section.  Whitespace around key and value is ignored.
List elements which do not contain an equal sign are skipped.

This property only works for Visual Studio 8 and above; it is ignored
on other generators.  The property only applies when set on a
directory whose CMakeLists.txt contains a project() command.

Note that CMake generates postSolution sections ExtensibilityGlobals
and ExtensibilityAddIns by default.  If you set the corresponding
property, it will override the default section.  For example, setting
VS_GLOBAL_SECTION_POST_ExtensibilityGlobals will override the default
contents of the ExtensibilityGlobals section, while keeping
ExtensibilityAddIns on its default.  However, CMake will always
add a ``SolutionGuid`` to the ``ExtensibilityGlobals`` section
if it is not specified explicitly.
