可能是这句起关键作用

    root@zhouqinan-Lenovo:/home/zhouqinan/projects/redis_dev/redis-plus-plus/build# cmake -DREDIS_PLUS_PLUS_CXX_STANDARD=11  -DREDIS_PLUS_PLUS_BUILD_TEST=OFF -DREDIS_PLUS_PLUS_BUILD_SHARED=OFF ..

历史命令

# 手动删除安装上去的库头文件
rm -rf /usr/local/include/sw/  
# 手动删除/usr/local/lib/hiredis/

用ldd命令来检查链接库
同时改动了CMakeLists.txt

直接上CMakeLists.txt

cmake_minimum_required(VERSION 3.10)   
set(CMAKE_CXXFLAGS "${CMAKE_CXX_FLAGS} -o3 --std=c++11  -lstdc++fs")

project(test_redis)  

find_package(OpenCV REQUIRED) 

include_directories(${OpenCV_INCLUDE_DIRS})

include_directories(/usr/local/include)
link_directories(/usr/local/lib)

add_executable(${PROJECT_NAME} test_redis.cpp)    
target_link_libraries(${PROJECT_NAME} redis++ hiredis ${OpenCV_LIBS} -lstdc++fs)

还有其他命令,感觉没生效

cmake -DREDIS_PLUS_PLUS_CXX_STANDARD=17 -DREDIS_PLUS_PLUS_BUILD_TEST=OFF -DREDIS_PLUS_PLUS_BUILD_SHARED=OFF ..
