paddleocr的cpp_infer在Liunx下编译部署

sh tools/build.sh

CMake Error at CMakeLists.txt:47 (find_package):

Could not find a package configuration file provided by "OpenCV" with any

of the following names:

OpenCVConfig.cmake

opencv-config.cmake

Add the installation prefix of "OpenCV" to CMAKE_PREFIX_PATH or set

"OpenCV_DIR" to a directory containing one of the above files. If "OpenCV"

provides a separate development package or SDK, be sure it has been

installed.

修改：

OPENCV_DIR=opencv3.4.7/opencv3 #不在编译的build下
LIB_DIR=your_paddle_inference_dir

将 "-o3" 改成 "-O3" 就可以了，修改后的结果如下，

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -g -O3 ${FLAG_OPENMP} -std=c++11")
