opencv裁剪和编译

0. 准备工作

0.1 下载和安装Eigen

地址

https://eigen.tuxfamily.org/index.php?title=Main_Page

对于opencv编译，需要增加EIGEN_INCLUDE_PATH和开启WITH_EIGEN

-DWITH_EIGEN=ON -DEIGEN_INCLUDE_PATH=./3rd/eigen-3.4.0

1. 实际脚本

编译脚本如下:

2. 使用opencv

将eigen编译后的产物复制到3rd或系统目录，如果是自定义目录则需要自己追加CMAKE_PREFIX_PATH

list(APPEND CMAKE_PREFIX_PATH "${CMAKE_SOURCE_DIR}/3rd/eigen-install")
find_package(Eigen3 REQUIRED)
# 先导入Eigen3
set(OpenCV_DIR "${CMAKE_CURRENT_SOURCE_DIR}/3rd/install/${ARCH}/vc17/staticlib")
find_package(OpenCV REQUIRED)
