Fixed an attribute in trianges.pyx that prevents compilation

[Gjacquenot]

I have updated a trianges.pyx since it is using a missing attribute.

I guess one wants RTC_GEOMETRY_STATIC instead of RTCGEOMETRY_STATIC.

https://github.com/embree/embree/blob/90e49f243703877c7714814d6eaa5aa3422a5839/include/embree2/rtcore_geometry.h#L72

The original error log is presented here

D:\Embree\pyembree>python setup.py build

Thanks for putting this in @Gjacquenot!

It seems as though include_path has been broken in some very recent (0.24) versions of Cython. I would rather we stay away from it. Was this line causing you problems for some reason?

[Gjacquenot]

Well, I did not have Cython. I installed it with pip, which gave me the lastest version( 0.27.3). With this version, I had the following error : ValueError: got unknown compilation option, please remove: include_dirs

With CI, we have the same error, as you can see: 57199d9

IMHO, I think you can accept it.

[scopatz]

Ahh yeah, I see the below now.

Great catch!

[Gjacquenot]

Thank you. I think you can rename the file trianges.pyx in triangles.pyx.

BTW, the example attenaute.py also creates an error

Thanks @Gjacquenot!

I have now released 0.1.2 with this fix!
