find_package(PCL 1.2 REQUIRED)使用CMake返回错误的路径

Question

我正在使用Ubuntu 12.04机器,我有以下问题:我正在尝试使用CMake编译和构建C++文件,但是当我在"cmake .."之后给出命令"make"时,我得到错误:

pcl_openni_grabber.cpp:2:29:致命错误:pcl/point_cloud.h:没有终止此类文件或目录编译.

现在我的CMakeLists.txt如下:

cmake_minimum_required(VERSION 2.8 FATAL_ERROR)

project(pcl-openni-grabber)

find_package(PCL 1.2 REQUIRED)

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

add_executable (pcl_openni_grabber pcl_openni_grabber.cpp)
target_link_libraries (pcl_openni_grabber ${PCL_LIBRARIES})

环境变量PCL_INCLUDE_DIRS包含的位置:

/usr/include/pcl-1.5

现在经过2个小时的工作来了解问题后,我在命令find_package()中找到了它.在实践中,当我运行"cmake .."时,它返回错误的pcl库(点云库)路径.确实这是"cmake .."的输出:

如您所见,它返回特定ros(Robot操作系统)包的pcl库的路径,该包通过"/ opt/ros"目录上的Synaptic Package Manager安装.正确的pcl库和包含在"/usr/include/pcl.1.5"和"/ usr/lib"中.

卸载ros时,find_package返回正确的路径,我能够编译和构建没有问题.但是因为我需要大学的ros,同时我需要cmake,我怎么能让cmake工作安装ros？任何的想法？

您可以在find_package命令中微调搜索路径:

find_package(PCL 1.2 REQUIRED PATHS /usr NO_DEFAULT_PATH)

这可能有点蛮力; /opt当CMake搜索包时,您可能会找到一种更好的排除方式.

另外,你可能不应该使用link_directories.文档说明了为什么通常不需要它.
