如何在CMake Makefile中包含OpenCV库 [英] How to include OpenCV libraries in CMake Makefile

问题描述

我希望你能帮助我。

我有一个简单的CMakeLists.txt为了构建我的项目Leopard 10.5.8。
我使用CMake 2.8.1，目前是代码：

I have a simple CMakeLists.txt in order to build my project on Leopard 10.5.8. I'm using CMake 2.8.1 and at the moment this is the code:

cmake_minimum_required(VERSION 2.8)
MESSAGE(STATUS "./src: Going into utils folder")
ADD_SUBDIRECTORY(utils)
MESSAGE(STATUS "./src: utils folder processed")

include_directories(${DIR}/headers)
link_directories (${DIR}/src/utils)

ADD_EXECUTABLE(sample sample.cpp)
TARGET_LINK_LIBRARIES(sample libSample ${EXTERNAL_LIBS})
INSTALL(TARGETS sample DESTINATION "./src")
MESSAGE(STATUS "./src: exiting src folder")

我需要在我的项目中添加OpenCV库。
当我使用Eclipse时，我将include路径设置为/ opt / local / include
，库路径设置为：/ opt / local / lib，然后指定库名称，例如__ opencv_core，opencv_imgproc，opencv_video

I need to add OpenCV libraries on my project. When I use Eclipse I set the include path to /opt/local/include and the libraries path to: /opt/local/lib and then I specify the libraries name such as_ opencv_core, opencv_imgproc, opencv_video.

您能告诉我如何在CMakeLists.txt文件中添加这些信息吗？

Can you tell me how to add these information in the CMakeLists.txt file, please?

我在官方的cmake常见问题中读到了一些信息，但我无法解决我的问题。

I've read some information in the official cmake FAQ but i wasn't able to solve my problem.

请帮帮我。

非常感谢。

推荐答案

您需要在TARGET_LINK_LIBRARIES命令中添加库名，添加他们没有lib前缀。例如：

You need to add the library names in the TARGET_LINK_LIBRARIES command, but you need to add them without the lib prefix. For example:

include_directories(${DIR}/headers /opt/local/include)
link_directories (${DIR}/src/utils /opt/local/lib)

ADD_EXECUTABLE(sample sample.cpp)
TARGET_LINK_LIBRARIES(sample opencv_core opencv_imgproc opencv_video ${EXTERNAL_LIBS})
