Error while build with OpenCV 3.1

[Diadlo]

Can build toxcore with tests. Have an error:

CMakeFiles/av_test.dir/testing/av_test.c.o: In function `cvPointFrom32f':
av_test.c:(.text+0x549): undefined reference to `cvRound'
av_test.c:(.text+0x55f): undefined reference to `cvRound'
CMakeFiles/av_test.dir/testing/av_test.c.o: In function `cvReadInt':
av_test.c:(.text+0xda5): undefined reference to `cvRound'
CMakeFiles/av_test.dir/testing/av_test.c.o: In function `cvEllipseBox':

av_test.c:(.text+0x1033): undefined reference to `cvRound'

Seems, OpenCV 3.1 hasn't cvRound function

[iphydf]

It does, but only in C++, but it still defines some inline C functions that use cvRound. Try the iphydf/opencv3 branch.

@iphydf Yes, it fixed. Thanks

opencv/opencv#6585 - either we use C++ (#160 does this) or require opencv<3.

[iphydf]

Fixed in #160.
