Fixed bug 3552 - Building SDL in release mode fails under VS 2017 RC 

Lukasz Biel

Tried to compile SDL2 using newest version of VS.

Got:
SDL_audiocvt.obj : error LNK2019: unresolved external symbol memcpy referenced in function SDL_ResampleCVT
1>E:\Users\dotPo\Lib\SDL\VisualC\x64\Release\SDL2.dll : fatal error LNK1120: 1 unresolved externals

whole compilation process: http://pastebin.com/eWDAvBce

Steps to reproduce:
clone http://hg.libsdl.org/SDL using tortoise hg,
open SDL\VisualC\SDL.sln,
when promted if should retarget solution click ok,
select release x64 build type,
Build/Build Solution

attempt 2, using Visual Studio cmake support:
open folder SDL\
select release x64 build type,
run CMake\Build CMakeLists.txt
build fails

When switched to debug build type, buils succeeds in both cases.
VS 2017 is still beta.
