在libtorch工程中添加一个dcn的库，编译出来的库名字是 /data_4/everyday/0902/snake/snake-refinenet/dcn_cpp_plugin/myinstall/lib/libdcn_v2_cuda_forward_v2.so
下面是完成的总的完成的正确的：
cmake_minimum_required(VERSION 3.0 FATAL_ERROR) project(snake-refinenet) SET(CMAKE_BUILD_TYPE "Debug") set(CMAKE_PREFIX_PATH "/data_4/everyday/0901/pytorch/torch") find_package(Torch REQUIRED) set(CMAKE_PREFIX_PATH "/home/yhl/software_install/opencv3.2") find_package(OpenCV REQUIRED) #include_directories("/data_4/everyday/0902/snake/snake-refinenet/dcn_cpp_plugin/dcn_v2.h") #link_directories("/data_4/everyday/0902/snake/snake-refinenet/dcn_cpp_plugin/myinstall/lib/libdcn_v2_cuda_forward_v2.so") #link_libraries(libdcn_v2_cuda_forward_v2) set(INC_DIR /data_4/everyday/0902/snake/snake-refinenet/dcn_cpp_plugin) set(LINK_DIR /data_4/everyday/0902/snake/snake-refinenet/dcn_cpp_plugin/myinstall/lib) include_directories(${INC_DIR}) link_directories(${LINK_DIR}) link_libraries(dcn_v2_cuda_forward_v2) add_executable(example-app example-app.cpp refine_det.cpp) target_link_libraries(example-app "${TORCH_LIBRARIES}") #target_link_libraries(example-app ${Boost_LIBRARIES}) target_link_libraries(example-app ${OpenCV_LIBS}) target_link_libraries(example-app dcn_v2_cuda_forward_v2) set_property(TARGET example-app PROPERTY CXX_STANDARD 11)一开始报错找不到 /usr/bin/ld: 找不到 -llibdcn_v2_cuda_forward_v2 /usr/bin/ld: 找不到 -llibdcn_v2_cuda_forward_v2
原来是要把lib去掉啊 link_libraries(dcn_v2_cuda_forward_v2) target_link_libraries(example-app dcn_v2_cuda_forward_v2)
