Issue description

When building godot-cpp or the recommended template inside the readme it fails to recognize the vsproj=yes command. I get the following error: WARNING: Unknown SCons variables were passed and will be ignored: vsproj=yes the build succeeds but is unable to generate vsproj.

Steps to reproduce

1. clone godot-cpp or godot-cpp template: https://github.com/godotengine/godot-cpp-template
2. Run command scons vsproj=yes
3. Observe that the build is successfully but without generating vsproj

There's no such option for godot-cpp, just for Godot itself, so this would be proposing a new feature
