Question

我是Computer Vision的新手。在Cmake上，我试图将PCL和OpenCV与2D激光雷达传感器一起使用。

我看到了这个教程：[http://unanancyowen.com/en/pcl18/#Download 1

要在CmakeLists.txt上配置PCL，请使用以下代码：

cmake_minimum_required( VERSION 2.8 )
# Create Project
project( solution )
add_executable( project main.cpp )
set_property( DIRECTORY PROPERTY VS_STARTUP_PROJECT "project" )

# Find Packages
find_package( PCL 1.8 REQUIRED )

if( PCL_FOUND )
  # Additional Include Directories
  # [C/C++]>[General]>[Additional Include Directories]
  include_directories( ${PCL_INCLUDE_DIRS} )

  # Preprocessor Definitions
  # [C/C++]>[Preprocessor]>[Preprocessor Definitions]
  add_definitions( ${PCL_DEFINITIONS} )
  #add_definitions( -DPCL_NO_PRECOMPILE )

  # Additional Library Directories
  # [Linker]>[General]>[Additional Library Directories]
  link_directories( ${PCL_LIBRARY_DIRS} )

  # Additional Dependencies
  # [Linker]>[Input]>[Additional Dependencies]
  target_link_libraries( project ${PCL_LIBRARIES} )
endif()

以及configure CmakeLists.txt for OpenCV，以下代码：

cmake_minimum_required( VERSION 3.6 )

# Create Project
project( solution )
add_executable( project main.cpp )
set_property( DIRECTORY PROPERTY VS_STARTUP_PROJECT "project" )

# Find OpenCV
set( OpenCV_DIR "C:/Program Files/opencv/build" )
find_package( OpenCV REQUIRED )

# Project Settings for OpenCV
if( OpenCV_FOUND )
  # Additional Include Directories
  # [C/C++]>[General]>[Additional Include Directories]
  include_directories( ${OpenCV_INCLUDE_DIRS} )

  # Additional Library Directories
  # [Linker]>[General]>[Additional Library Directories]
  link_directories( ${OpenCV_LIB_DIR} )

  # Additional Dependencies
  # [Linker]>[Input]>[Additional Dependencies]
  target_link_libraries( project ${OpenCV_LIBS} )
endif()

如何让CmakeLists.txt与两者一起使用？ PCL和OpenCV。

在网站上找到答案，我得到了这些文件： http://unanancyowen.com/en/pcl18/#comment-1221

这是拉取OpenCV和PCL的代码：

cmake_minimum_required( VERSION 2.8 )
# Create Project
project( solution )
add_executable( project main.cpp )

# Set StartUp Project (Option)
# (This setting is able to enable by using CMake 3.6.0 RC1 or later.)
set_property( DIRECTORY PROPERTY VS_STARTUP_PROJECT "project" )

# Find Packages
# Find PCL
find_package( PCL 1.8 REQUIRED )

# Find OpenCV
set( OpenCV_DIR "C:/Program Files/opencv/build" )
find_package( OpenCV REQUIRED )

if( PCL_FOUND AND OpenCV_FOUND )
  # [C/C++]>[General]>[Additional Include Directories]
  include_directories( ${PCL_INCLUDE_DIRS} )
  include_directories( ${OpenCV_INCLUDE_DIRS} )

  # [C/C++]>[Preprocessor]>[Preprocessor Definitions]
  add_definitions( ${PCL_DEFINITIONS} )

  # For Use Not PreCompiled Features 
  #add_definitions( -DPCL_NO_PRECOMPILE )

  # [Linker]>[General]>[Additional Library Directories]
  link_directories( ${PCL_LIBRARY_DIRS} )
  link_directories( ${OpenCV_LIB_DIR} )

  # [Linker]>[Input]>[Additional Dependencies]
  target_link_libraries( project ${PCL_LIBRARIES} )
  target_link_libraries( project ${OpenCV_LIBS} )
endif()

关于这个link，有一个旧的解释，这里是关于OpenCV here的问题。

Answer 2

要在同一项目中同时使用PCL和OpenCV，可以在最小行中编写CMakeLists.txt文件，如下所示：

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(project_name)

find_package(PCL 1.4 REQUIRED)
find_package(OpenCV REQUIRED)

include_directories(${PCL_INCLUDE_DIRS} )
link_directories(${PCL_LIBRARY_DIRS} )
add_definitions(${PCL_DEFINITIONS} )

add_executable (project_executable main.cpp)
target_link_libraries (project_executable ${PCL_LIBRARIES} ${OpenCV_LIBS})

将Cmake与PCL和OpenCV一起使用
