【记录】Opencv+LibTorch安装

环境Ubuntu20.04。

[Opencv]源码编译：Linux系统下opencv3.4.1安装教程

[LibTorch]下载已编译版本：在Ubuntu下安装LibTorch

[磁盘空间不足]vmware中ubuntu虚拟机扩容

CMakeLists.txt(替换成自己的路径):

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(idc)

find_package(OpenCV REQUIRED)

message(STATUS "OpenCV library status:")
message(STATUS "    version: ${OpenCV_VERSION}")
message(STATUS "    libraries: ${OpenCV_LIBS}")
message(STATUS "    include path: ${OpenCV_INCLUDE_DIRS}")

set(Torch_DIR /home/shen/ICSim/testc/testids/libtorch/share/cmake/Torch)

find_package(Torch REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(${OpenCV_LIBS})
include_directories(${TORCH_INCLUDE_DIRS})
add_executable(IDS IDS.cpp)
target_link_libraries(IDS
	"${TORCH_LIBRARIES}"
	${OpenCV_LIBS}
	)

set_property(TARGET IDS PROPERTY CXX_STANDARD 14)

编译方式：

cmake .
make

编译出错后删除CMakeCache.txt再重新编译。
