So, I did look at how to fix this some.  I have a c# program that can 
force a running visual studio process to close and reload the solution 
it has.  The idea would be to have cmake run this when cmake is run as 
part of the build.  However, visual studio has a neat trick of killing 
all processes launched as part of a build.  So, what happens is the 
reload c# program closes the solution, and VS kills it before it can 
reload the project.  The only way around this is to run some sort of 
cmake IDE VS reload server, that cmake can contact and ask it to force a 
reload.  Does this sound worth while?  It could also unload/load, and 
build.  However, I am not sure we want to restart the build.
