ubuntu 12.04 编译 openvc + ipp 7.1 USE IPP NO 的问题
??-D USE_TBB=ON ? 这样写就不行了 ， 应该是 ?WITH_TBB=ON?cmake?-D WITH_TBB=ON? ?-D?WITH_TBB=ON??-D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..改了 ? ?又报了一些错误，不管怎么样，总算有点参考信息了看了OpenCVFindIPP.cmake 文件IPP_PATH ?这个属性有时老的，新的应该是 IPPROOT?设置 ? ?export ?IPPROOT=/opt/intel/composer_xe_2013.1.117/ipp/ ??开始重新CMAKE ? ?又出错了CMake Error at cmake/OpenCVFindIPP.cmake:180 (message):?
