问题
在Ubuntu18.04下采用编译安装opencv4，在make和make install后想用pkg-config查找opencv发现提示没有找到
~ pkg-config --libs opencv4
Package opencv4 was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv4.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv4' found
后来查找资料发现在cmake编译配置时候需要添加-D OPENCV_GENERATE_PKGCONFIG=YES
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -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 -D OPENCV_GENERATE_PKGCONFIG=YES -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules ..
这样编译就可以使用pkg-config检测
