License Issue.

Hello,

I'm using embree 1.x and following the new features of embree 2.x.

I notice an issue inside licensing. It is really important for me and do not enable me to evolve toward embree 2.x.

Embree is license under Apache 2.0 License, but recently TBB was introduces inside embree. TBB is based on GPL v2, which is imcompatible with Apache. It convert Apache license to make it GPL v2 like TBB.

Have you notice this issue ?

It seems we can use embree without TBB, should it not be the default value instead of TBB ?

Please note that TBB is not released under the GPLv2 license but the "GPLv2 license with the runtime exception" (https://www.threadingbuildingblocks.org/licensing). Further, you can also just use Embree without TBB.

Hello Sven,

Yes you are right, my mistake, I didn't notice this exception, and I thought it was invasive, but it is not with this exception.

I got no more excuse to use your great code inside embree 2 :)

Many thanks
