将外部库添加到CMakeList.txt c ++ [英] Add external libraries to CMakeList.txt c++

问题描述

我有我的外部库，如下图所示，我创建后的符号链接：

以及与其他文件中的库相关的标题：

我使用ROS，我需要添加这些库到我的包到CmakeList.txt：

  cmake_minimum_required（VERSION 2.4.6）
 include（$ ENV {ROS_ROOT } /bt/rosbuild/rosbuild.cmake）
 
 rosbuild_init（）
 
 #set构建可执行文件到bin目录的默认路径
 set（EXECUTABLE_OUTPUT_PATH $ {PROJECT_SOURCE_DIR} / bin）
＃设置构建库到lib目录的默认路径
 set（LIBRARY_OUTPUT_PATH $ {PROJECT_SOURCE_DIR} / lib）
 
 #common命令用于构建c ++可执行文件和库
 #rosbuild_add_library（$ {PROJECT_NAME} src / example.cpp）
 #target_link_libraries（$ {PROJECT_NAME} another_library）
 #rosbuild_add_boost_directories（）
 #rosbuild_link_boost （$ {PROJECT_NAME} thread）
 #rosbuild_add_executable（example example / example.cpp）
 #target_link_libraries（example $ {PROJECT_NAME}）
 
 rosbuild_add_executable（kinectueye src / kinect_ueye.cpp ）
  

所以我的问题是如何添加这些文件夹（我认为我需要的第一个添加我不确定）到我的CmakeList.txt文件，以便我可以使用我的程序中的类和方法。

解决方案

我将从升级CMAKE版本开始。

=http://www.cmake.org/cmake/help/v2.8.12/cmake.html#command%3ainclude_directories> INCLUDE_DIRECTORIES 的标题位置和 LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries

  INCLUDE_DIRECTORIES（your / header / dir）
 LINK_DIRECTORIES（您的/ library / dir）
 rosbuild_add_executable（kinectueye src / kinect_ueye.cpp）
 TARGET_LINK_LIBRARIES（kinectueye lib1 lib2 lib2 ...）
   lib1 已扩展为 liblib1.so  <$ c $ p> 
 $ b < （在Linux上），因此使用ln 创建适当的链接（如果您没有这些链接）
 
I have my extern library as shown in this picture that I create the symbolic links after:

https://imagizer.imageshack.us/v2/682x472q90/840/pn.png

and the headers related to the library in other file:

https://imagizer.imageshack.us/v2/682x374q90/855/tjrh.png

I working with ROS and I need to add these libraries to my package to CmakeList.txt:
cmake_minimum_required(VERSION 2.4.6)
include($ENV{ROS_ROOT}/core/rosbuild/rosbuild.cmake)

rosbuild_init()

#set the default path for built executables to the "bin" directory
set(EXECUTABLE_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/bin)
#set the default path for built libraries to the "lib" directory
set(LIBRARY_OUTPUT_PATH ${PROJECT_SOURCE_DIR}/lib)

#common commands for building c++ executables and libraries
#rosbuild_add_library(${PROJECT_NAME} src/example.cpp)
#target_link_libraries(${PROJECT_NAME} another_library)
#rosbuild_add_boost_directories()
#rosbuild_link_boost(${PROJECT_NAME} thread)
#rosbuild_add_executable(example examples/example.cpp)
#target_link_libraries(example ${PROJECT_NAME})

rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
So my question is how can I add these folders (I think the first one that I need to add I'm not sure) to my CmakeList.txt file so as I can use the classes and the methods in my program.

Thank you.
解决方案
I would start with upgrade of CMAKE version.

You can use INCLUDE_DIRECTORIES for header location and LINK_DIRECTORIES + TARGET_LINK_LIBRARIES for libraries
INCLUDE_DIRECTORIES(your/header/dir)
LINK_DIRECTORIES(your/library/dir)
rosbuild_add_executable(kinectueye src/kinect_ueye.cpp)
TARGET_LINK_LIBRARIES(kinectueye lib1 lib2 lib2 ...)
note that lib1 is expanded to liblib1.so (on Linux), so use ln to create appropriate links in case you do not have them
