CMake 和点云库的链接器错误

Question

我尝试安装 PointCloud 库并将其添加到我的项目中，但总是遇到链接器错误。这是我的 Cmake 文件：

cmake_minimum_required(VERSION 2.8)

project(OpenCV-BATest)

set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
set(SOURCES regression.h)

find_package(Qt5Core)
find_package( OpenCV REQUIRED )
find_package(PCL 1.3 REQUIRED COMPONENTS common io)
include_directories(${PCL_INCLUDE_DIRS})
INCLUDE_DIRECTORIES(${OpenCV_INCLUDE_DIRS})

add_executable(${PROJECT_NAME} "main.cpp")

target_link_libraries(${PROJECT_NAME} Qt5::Core ${OpenCV_LIBS} ${PCL_COMMON_LIBRARIES} ${PCL_IO_LIBRARIES})

有趣的是 OpenCV 库，我也是这样做的，没有创建任何“未定义的引用..”错误，但只有 PCL 库。

Answer 1

找到答案了，应该加进去

target_link_libraries(${PROJECT_NAME} Qt5::Core ${OpenCV_LIBS} ${PCL_LIBRARIES})

改为。
