OpenCV compatible definition of int64

I had the same problem.

I don’t know if my approach was the best but I have changed OpenCV directly instead of Unreal

I had to change "opencv2/core/types_c.h"

I changed the code below:

#else
   typedef int64_t int64;
   typedef uint64_t uint64;
#  define CV_BIG_INT(n)   n##LL
#  define CV_BIG_UINT(n)  n##ULL
#endif

By the the following code:

#else
    typedef long long int64;
    typedef unsigned long long uint64;
#  define CV_BIG_INT(n)   n##LL
#  define CV_BIG_UINT(n)  n##ULL
#endif

No Unreal and OpenCV works.
