Add examples to a common folder in visual studio

Groups examples in a common folder on visual studio

Thank you! Yeah I was lazy and did this for all other repositories except this one :)

I don't use VS myself and don't really remember how the project tree looks there but ... isn't grouping of all examples together too coarse? Or does VS itself make subfolders based on the executable?

If it makes subfolders then it's probably fine like this, and it'd be enough to have just a single

# IDE folder in VS, Xcode etc. CMake 3.12+, older versions have only the FOLDER
# property that would have to be set on each target separately.
set(CMAKE_FOLDER "MagnumExamples")

at the top of src/CMakeLists.txt. That'd do it the same way as in other projects.

As it is, it ends up creating 1 folder with all the example projects inside.

A single set(CMAKE_FOLDER "MagnumExamples") would probly be more maintainable (less code to add per new example)

[mosra]

Can you screenshot it for me? :) Just so I have an idea how it looks like and how much worse it would get for VS in case someone would want subfolders instead. The FOLDER property is also doing similar grouping in Xcode, and there it behaves a bit different IIRC.

Thank you!

Heres my solution: (4 examples enabled)

[mosra]

Oh, that looks great actually, thanks.

I'll hunt for the MagnumPlugins-headers and fix it too. Let me know if there are any other similar orphans.

Pushed as 74496c1, the loose MagnumPlugins-headers target is fixed in mosra/magnum-plugins@7a438d0.

Thank you!
