卸载源码安装的cmake：
进入安装cmake的工作目录，有文件install_manifest.txt文件，记录着安装的文件，全部删除即可，执行

cat install_manifest.txt | sudo xargs rm

2. cmake Cannot create package registry file:

Qt下设置

CMAKE_EXPORT_NO_PACKAGE_REGISTRY=ON
CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY=ON

3. string sub-command REGEX, mode REPLACE needs at least 6 arguments total to command.

将

string(REGEX REPLACE "-O0" "-Og" CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG})

替换为

string(REGEX REPLACE "-O0" "-Og" CMAKE_CXX_FLAGS_DEBUG "${CMAKE_CXX_FLAGS_DEBUG}")

SET(OpenCV_DIR /usr/local/share/OpenCV)
find_package(OpenCV REQUIRED)
