The vscproj SCons target is what produces a Visual Studio project and is very handy for people who develop on Windows, with VS. With the old ninja generator I could just run ninja vcxproj and get a VS project, but the new ninja generator doesn't seem to produce one:

E:\workspace\mongo>ninja vcxproj
ninja: error: unknown target 'vcxproj'

E:\workspace\mongo>ninja compiledb
[0/1] Building compile_commands.json

It should be on the same parity as compiledb.
