我正在使用 Ubuntu 12.04 机器，但遇到以下问题：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，出现错误：
pcl_openni_grabber.cpp:2:29：致命错误：pcl/point_cloud.h：没有此类文件或目录编译终止。
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})
其中环境变量 PCL_INCLUDE_DIRS 包含：
/usr/include/pcl-1.5
现在经过 2 个小时的工作来了解问题，我在命令 find_package() 中找到了它。实际上，当我运行“cmake ..”时，它会将错误的路径返回到 pcl 库（点云库）。事实上，这是“cmake ..”的输出：

如您所见，它返回通过 Synaptic 包管理器安装在“/opt/ros”目录中的特定 ros（机器人操作系统）包的 pcl 库的路径。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，我可以毫无问题地编译和构建。但是因为我需要 ros 上大学，同时我需要 cmake，我如何让 cmake 在安装了 ros 的情况下工作？任何想法？
