how to set sdl2 path

[chuyuwei]

I put SDL2.0 in C:\Users\chuyuwei\Desktop\duallerp\magnum-bootstrap\SDL2-2.0.10. So how should I write in cmake
it always shows
Could NOT find SDL2 (missing: SDL2_LIBRARY)
CMake Error at magnum/src/Magnum/Platform/CMakeLists.txt:289 (message):
SDL2 library, required by Sdl2Application, was not found. Set
WITH_SDL2APPLICATION to OFF to skip building it.

it is vs 2017

If that directory contains prebuilt SDL binaries (it's the SDL2-devel-2.0.10-VC.zip file), it should be enough to make the root CMakeLists look like this:

cmake_minimum_required(VERSION 3.1)
project(MyApplication)

set(CMAKE_MODULE_PATH "${PROJECT_SOURCE_DIR}/modules/" ${CMAKE_MODULE_PATH})

# Add Corrade and Magnum as subprojects, add prebuilt SDL and enable Sdl2Application
list(APPEND CMAKE_PREFIX_PATH "${PROJECT_SOURCE_DIR}/SDL2-2.0.10")
set(WITH_SDL2APPLICATION ON CACHE BOOL "" FORCE)
add_subdirectory(corrade)
add_subdirectory(magnum)

add_subdirectory(src)

This seems to be the easiest, I'll mention it in the Getting Started guide.

Getting Started Guide updated in 6b64ee6 and verified to be working. It should be now much easier to follow, with less pain points for Windows users.
