Cannot build EmulationStation (VS2015) from CMake solution file

I'm having difficulties trying to compile an opensource framework (EmulationStation) in VS2015 on Windows. I've never used any of the tools before, apart from Visual Studio - so please forgive me if these are some obvious mistakes.

The guide says i need to do like this:

Boost (you'll need to compile yourself or get the pre-compiled binaries)

Eigen3 (header-only library)

FreeImage

FreeType2 (you'll need to compile)

SDL2

cURL (you'll need to compile or get the pre-compiled DLL version)

(Remember to copy necessary .DLLs into the same folder as the executable: probably FreeImage.dll, freetype6.dll, SDL2.dll, libcurl.dll, and zlib1.dll. Exact list depends on if you built your libraries in "static" mode or not.)

CMake (this is used for generating the Visual Studio project)

(If you don't know how to use CMake, here are some hints: run cmake-gui and point it at your EmulationStation folder. Point the "build" directory somewhere - I use EmulationStation/build. Click configure, choose "Visual Studio [year] Project", fill in red fields as they appear and keep clicking Configure (you may need to check "Advanced"), then click Generate.)

This is how my CMake looks like (it says generating done)

I get alot of compilation errors in visual studio when trying to build though:

1) Cannot open include file: 'curl/curl.h': No such file or directory (compiling source file C:\Users\retropie\Documents\GitHub\EmulationStation\es-app\src\guis\GuiMetaDataEd.cpp) emulationstation C:\Users\retropie\Documents\GitHub\EmulationStation\es-core\src\HttpReq.h

Where do i get this header file from?

2) 'round': redefinition; different exception specifications (compiling source file C:\Users\retropie\Documents\GitHub\EmulationStation\es-app\src\guis\GuiMenu.cpp) emulationstation C:\Users\retropie\Documents\GitHub\EmulationStation\es-core\src\Util.h 18

I have a lot of these errors with 'round'. Am i missing a reference to a library?

Another screendump of some of the errors from VS2015:

Hope someone can point me in the right direction.
