ros error : c++: error: $(catkin_LIBRARIES): 没有那个文件或目录

  卧槽，真是。。。。。。。。。。。。。。。。。。。。。。。。瞎眼了。

  一个半小时才找出错误来。。。。。

 

c++: error: $(catkin_LIBRARIES): 没有那个文件或目录

  Oh my God! I´m quite blind .... apologies for any inconvenience. I need my glasses to see ... I´m absolutely a disaster. It was exactly what you said to me. I didn´t realice it. ${catkin_LIBRARIES} rather than $(catkin_LIBRARIES). Thanks a lot!

  我都要崩溃了。。。。。。。。

 另一个错误：

Could not find a package configuration file provided by "PCL" (requested
  version 1.2) with any of the following names:
    PCLConfig.cmake
    pcl-config.cmake
  Add the installation prefix of "PCL" to CMAKE_PREFIX_PATH or set "PCL_DIR"
  to a directory containing one of the above files.  If "PCL" provides a
  separate development package or SDK, be sure it has been installed.
-- Configuring incomplete, errors occurred!

   我的CmakeLists.txt:

 

cmake_minimum_required(VERSION 2.8.3)
project(second_pcl)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package( PCL REQUIRED)    #这个可能要单独写出来
find_package(catkin REQUIRED
     roscpp rospy pcl_conversions pcl_ros sensor_msgs
# PCL REQUIRED
)

#find_package( PCL REQUIRED)

include_directories(include ${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})

add_executable(pcl_create  src/pcl_create.cpp )
target_link_libraries(pcl_create   ${catkin_LIBRARIES}   ${PCL_LIBRARIES})

   这下没问题了，遇到这个错误，期间还自己重新编译了 PCL 包 。。。但应该还是CmakeLists.txt里的错误
