LibTorch and OpenCV Libs not working in same cmakelist file

Question

cmake_minimum_required(VERSION 3.1 FATAL_ERROR)
project(Detect)
#set(Torch "/home/somnath/libtorch/share/cmake/Torch")
find_package(Torch REQUIRED)
find_package(OpenCV REQUIRED)
message(STATUS "CVINCLUDE: ${OpenCV_INCLUDE_DIRS}")
include_directories(${OpenCV_INCLUDE_DIRS})
add_executable(Detect main.cpp)
target_link_libraries(Detect  ${TORCH_LIBRARIES}; ${OpenCV_LIBS})

${TORCH_LIBRARIES}; ${OpenCV_LIBS} both are not working at the same time if want to use to build the code.

Please, elaborate "not working": what is happened, what error do you get, etc. — Tsyvarev

No, do not use screenshots for error messages and code: meta.stackoverflow.com/questions/285551/…. Instead, copy paste the error message into the question post as text. See also How to Ask. — Tsyvarev

Try to change the libTorch from Pre-cxx11 ABI to cxx11 ABI

I had face the same problem. Spent 20+hrs to change CMake file and what not...But there is nothing to do with CMakeLIsts.txt ..Just comment "using namespace cv" if you have in your code...It worked for me. Hope it solves your problem.

Thanks.

If you look at the error you see they are using the fully qualified name (cv::foo), so using namespace cv wouldn't help.
