[CMake] How to change default target in solution?

[aaron.meadows at thomsonreuters.com]

Sorry, the .sln is what I meant by "the solution file generated by
CMake".  Thanks for catching that, it wasn't clear the way I wrote it.
=D  English fail!  

When I was smashing around in the solution file to try and get ALL_BUILD
to be the default project but also have it stored in the
PREDEFINED_TARGETS_FOLDER, I couldn't make sense of the choices it made
based on the ordering.

Really, Default Project doesn't make much sense in any case beyond the
most simple development effort.  I was trying to find someone that knew
why it's such a big requirement to have ALL_BUILD set as the default.
That was apparently the reason the change for Solution Folders which put
ALL_BUILD in the PREDEFINED_TARGETS_FOLDER was reverted.  As the author
of that patch commented, ALL_BUILD doesn't even do anything if you "run"
it in the debugger, so why is it such a big deal to have it the Default
Project?

Weird.

Actually, I think that VS picks the default target based on the order 
that it shows up in the .sln file.  I have never gotten around to 
verifying this or seeing if there was a way to add a property that would

do the re-order.  But, if this does work, it might actually be possible 
to implement this.
