opencv - 如何使用 CMake (ubuntu 14.04) 将 opencv 链接到 ROS indigo (catkin)

Question

我目前无法使用 cv_bridge。我收到这个编译错误

CMake Error at /opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake:106 (message):
  Project 'cv_bridge' specifies '/usr/include/opencv' as an include dir,
  which is not found.  It does neither exist as an absolute directory nor in
  '/opt/ros/indigo//usr/include/opencv'.  Ask the maintainer ..

可能是我的 CMake 中的问题(...？)

cmake_minimum_required(VERSION 2.8.3)
project(XY)

find_package(catkin REQUIRED COMPONENTS
cv_bridge
image_transport
roscpp
rospy
std_msgs
)

#set(OpenCV_DIR "/usr/local/lib/opencv")
find_package(OpenCV REQUIRED core imgproc highgui PATHS /home/polar/soft/lib/opencv/opencv-3.1.0/cmake)
include_directories( ${OpenCV_INCLUDE_DIRS} )

if(OpenCV_FOUND)
# include_directories(${Boost_INCLUDE_DIRS})
message("\n\n OpenCV found!!!! \n\n")   
endif()

关于问题的原因和解决方法的任何想法？我过去一直在使用 ROS fuerte，从来没有遇到过这样的问题....

最后，我修改了文件/opt/ros/indigo/share/cv_bridge/cmake/cv_bridgeConfig.cmake

我变了

set(cv_bridge_FOUND_CATKIN_PROJECT TRUE)

if(NOT "include;/usr/include/opencv;/usr/include " STREQUAL " ")
  set(cv_bridge_INCLUDE_DIRS "")
  set(_include_dirs "include;/usr/include/opencv;/usr/include")

到

set(cv_bridge_FOUND_CATKIN_PROJECT TRUE)
if(NOT "include;/usr/local/include/opencv" STREQUAL " ")
  set(cv_bridge_INCLUDE_DIRS "")
  set(_include_dirs "/usr/local/include/opencv;/usr/include;/usr/local/include")

事实上我只是把usr/include改成了/usr/local/include。这解决了我的问题。但我认为这不是正确的做法 (?)。
