-DURHO3D_SSE=ON Has no effect

(Only Tested On Windows)

I have -DURHO3D_SSE=ON in cmake: But looking at Matrix3x4.h: URHO3D_SSE is not defined:

This can be fixed by removing the following "Trimming" code from the end of Urho3D.h:

// Disable SSE if compiler does not support it.
#if defined(URHO3D_SSE) && !defined(__SSE2__) && (!defined(_M_IX86_FP) || _M_IX86_FP < 2)
#   undef URHO3D_SSE
#endif

MSVC seems to have an issue with the

!defined(__SSE2__)

part of the condition.
__SSE2__ is defined in SDL but the whole expression is evaluated to true.

Relevant targets might need sse being enabled through compiler flags
