Hi.
I’m trying to use the prebuilt libraries for Cocos2dx v3.12 on Windows using CMake (v3.4.1) with MSVC 14 (VS2015).
I both ran the cocos gen-lib and compiled the library with the Visual Studio files.
But I get the following errors when I try to compile my game with the resulted libraries.
AppDelegate.cpp.obj:-1: error: LNK2001: unresolved external symbol "public: static int const cocos2d::Scheduler::PRIORITY_SYSTEM" (?PRIORITY_SYSTEM@Scheduler@cocos2d@@2HB)
HelloWorldScene.cpp.obj:-1: error: LNK2001: unresolved external symbol "public: static class cocos2d::Vec2 const cocos2d::Vec2::ZERO" (?ZERO@Vec2@cocos2d@@2V12@B)
Here’s my CMakeLists.txt file:

Does v3.12 support VS 2015? I also tried building a game with the default CMakeLists file but I got libpng-2015.lib not found error.
