[CMake] Building both make files and visual studio files.

[Josef Karthauser]

Hello again,

I'm wondering what the best way to going about producing make files and
visual studio files at the same time is.  I want to use nmake to build
my tree, but want visual studio project files so that the developers can
continue to with within the visual studio environment, which would call
the make as an external build tool.

Does anyone do anything like this?  I'm really new to cmake, and so am
still working out the ropes.  I apologise if this is a really obvious
question.

Thanks,
Joe
