error C2065: 'M_PI': undeclared identifier

[liudonghua123]

I tried to build it on windows according to the readme. But during the build process, I saw the error D:\code\c_cpp\uMario_Jakowski\uNext\FireBall.cpp(21,20): error C2065: 'M_PI': undeclared identifier [D:\code\c_cpp\uMario_Jakowski\build\uMario.vcxproj].

CMake Warning (dev) at CMakeLists.txt:13 (elseif):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted variables like "MSVC" will no longer be dereferenced when the policy
  is set to NEW.  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

[liudonghua123]

I found this link https://stackoverflow.com/questions/26065359/m-pi-flagged-as-undeclared-identifier.

So I added the following code to FireBall.cpp:5, then I can build successfully.

#ifdef _WIN32
#include <corecrt_math_defines.h>
#endif

updated: use the following maybe better.

#if defined(_WIN32) || defined(WIN32) 
#include <corecrt_math_defines.h>
#endif

[liudonghua123]

I write a simple pr #20.
