[cmake-developers] Visual studio CLR Support

[J Decker]

In the property group for 'configuration' there is a field
<CLRSupport>true</CLRSupport> which is set and exists if CLR support
is enabled.  I have set the flags on all of the projects; but I don't
know if there's a way to turn this one, and this controls how the
project reacts, for instance when adding references, without this
flag, you can only select other projects as dependencies, whereas when
it's enabled, you can add .NET references for things like 'System'.
