Errors while building OpenCV 3.0.0 with -D BUILD_TBB flag.
Originally, I wanted to compile opencv 3.0.0 with TBB support on my Raspberry pi. However, libtbb-dev is not available on official raspbian repository. So, I decided to compile OpenCV 3.0.0 from the source to with -D BUILD_TBB=ON -D WITH_TBB=ON cmake flags. It threw me following errors.

So, I decided to compile OpenCV 2.4.9 with the same cmake flags and it worked fine. To see if it's an Rpi problem or -D BUILD_TBB=ON problem, I decided to compile OpenCV 3.0.0 on my ubuntu 15.04 machine with the same cmake configuration and it threw me the same error. What do I need to do to fix this problem ? Has anyone faced the same problem ? I appreciate the help. Thanks.
Update:
I also tried changing tbb source file (in 3rdparty/tbb/CMakeList ...
I am not sure but with TBB it seems that there is two configuation one with dll and another where you build tbb your self I think.
In cmake you have got flag WITH_TBB and and another flag BUILD_TBB. In my configuration I have got only TBB dll so I use with_tbb May be there is same difference on linux
PS I haven't got my configuration so I cannot check which flag I use with TBB DLL on windows 7 opencv 3.0 gold
@LBerger You're correct, ie you can make use of already installed libraries (like you mentioned with dll) or you can build a 3rd party library from source at the time of building OpenCV as per I understand and BUILD_TBB is for later option, ie, building on the go as you compile OpenCV.
