使用Cmake配置c ++ OpenCV项目 [英] Configuring an c++ OpenCV project with Cmake

问题描述

我认为这是创建使用OpenCV库的项目的基本步骤，因此您不需要手动包括所有的库。没有关于这个主题的详细信息，至少对于刚刚想要使用OpenCV的新手来说，可以这样：

I consider this a fundamental step for creating projects that use OpenCV libraries so you don't need to manually include all the libraries. There is not detailed information on this topic, at least for a newbie that just wants to use OpenCV as soon as posible, so:

这是最简单的可扩展的方式使用Cmake创建多平台c ++ OpenCV

推荐答案

包含两个子文件夹 src 和包含的文件夹项目以及名为 CMakeLists.txt 的文件。

First: create a folder Project containing two subfolders src and include, and a file called CMakeLists.txt.

第二：将cpp放在src文件夹和头文件include文件夹中。

Second: Put your cpp inside the src folder and your headers in the include folders.

第三：您的CMakeLists.txt应如下所示：

Third: Your CMakeLists.txt should look like this:

cmake_minimum_required(VERSION 2.8) 
PROJECT (name)
find_package(OpenCV REQUIRED )
set( NAME_SRC
    src/main.cpp    
)

set( NAME_HEADERS       
     include/header.h
)

INCLUDE_DIRECTORIES( ${CMAKE_CURRENT_SOURCE_DIR}/include )
link_directories( ${CMAKE_BINARY_DIR}/bin)
set(EXECUTABLE_OUTPUT_PATH ${CMAKE_BINARY_DIR}/bin)
add_executable( name ${NAME_SRC} ${NAME_HEADERS} )

target_link_libraries( sample_pcTest ${OpenCV_LIBS} )

第四：打开CMake GUI并选择根文件夹作为输入，并为输出创建一个构建文件夹。单击配置，然后生成，并选择生成器（VisualStudio，Eclipse，...）

Fourth: Open CMake GUI and select the root folder as input and create a build folder for the output. Click configure, then generate, and choose the generator (VisualStudio, Eclipse, ...)
