ROS：找不到包配置文件

Question

编辑：好的，所以我决定尝试一些随机的东西，我有罗斯比也口述作为一个必要的组成部分。我从我的cmakelists文件中删除了所有OpenCV的内容，现在它只显示了与rospy相同的错误，以及与std-msg相同的处理。我第一次开始用ROS在这台电脑上，我正在用ROS教程，一切都很好，直到这一点。。

我知道很多人对此都有麻烦，运行catkin-make/cmake，发现它找不到你的OpenCV文件：

Could not find a package configuration file provided by "OpenCV" with any
  of the following names:

    OpenCVConfig.cmake
    opencv-config.cmake

当我尝试使用roscpp、rospy等时也出现了这个错误：

  Could not find a package configuration file provided by "roscpp" with any
  of the following names:

roscppConfig.cmake
roscpp-config.cmake

到目前为止我试过的是： 导出OpenCV_DIR、CMAKE_PREFIX_PATH等。人们在堆栈上建议的大多数内容。仍然会出现这个错误。 检查以确保OpenCV安装正确，使用IDMTEST，我发现一切都是正确的。我可以很好地将opencv与python等一起使用

以及Tsyvarev从评论中得到的解决方案： 如果是简单的find_包（OpenCV），那么任何一个都应该有帮助：1。cmake-DOpenCV_DIR=/usr/share/OpenCV。。。。2。cmake-DCMAKE_PREFIX_PATH=/usr。三。导出CMAKE_PREFIX_PATH=/usr。

这些.cmake文件位于： /usr/共享/OpenCV 和 /usr/local/share/OpenCV

不确定他们是否能被定位在其他地方，试着做了一个大规模的搜索，它似乎只是指向这两个特定的文件夹

浏览了我的CMakeLists.txt文件，并按照.cmake文件的指示添加了目录、目标库等

我真的不知道现在该怎么办。

一些代码/文件：

    cmake_minimum_required(VERSION 2.8.3)

## System dependencies are found with CMake's conventions
# find_package(Boost REQUIRED COMPONENTS system)


## Uncomment this if the package has a setup.py. This macro ensures

## Declare ROS messages, services and actions ##
################################################

## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
##   * add a build_depend tag for "message_generation"
##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
##   * If MSG_DEP_SET isn't empty the following dependency has been pulled in
##     but can be declared for certainty nonetheless:
##     * add a run_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
##   * add "message_generation" and every package in MSG_DEP_SET to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * add "message_runtime" and every package in MSG_DEP_SET to
##     catkin_package(CATKIN_DEPENDS ...)
##   * uncomment the add_*_files sections below as needed
##     and list every .msg/.srv/.action file to be processed
##   * uncomment the generate_messages entry below
##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)

## Generate messages in the 'msg' folder
 add_message_files(
   FILES
   Num.msg

 )

## Generate services in the 'srv' folder
 add_service_files(
   FILES
   AddTwoInts.srv
 )

## Generate actions in the 'action' folder
# add_action_files(
#   FILES
#   Action1.action
#   Action2.action
# )

## Generate added messages and services with any dependencies listed here
 generate_messages(
   DEPENDENCIES
   std_msgs  # Or other packages containing msgs
 )

## Declare ROS dynamic reconfigure parameters ##
################################################

## To declare and build dynamic reconfigure parameters within this
## package, follow these steps:
## * In the file package.xml:
##   * add a build_depend and a run_depend tag for "dynamic_reconfigure"
## * In this file (CMakeLists.txt):
##   * add "dynamic_reconfigure" to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * uncomment the "generate_dynamic_reconfigure_options" section below
##     and list every .cfg file to be processed

## Generate dynamic reconfigure parameters in the 'cfg' folder
# generate_dynamic_reconfigure_options(
#   cfg/DynReconf1.cfg
#   cfg/DynReconf2.cfg

Answer 1

 Could not find a package configuration file provided by "roscpp" with
 any of the following names:

         roscpp-config.cmake

如果ROS是一个依赖项而它没有安装，就会发生这种情况。从这里安装：http://wiki.ros.org/ROS/Installation并重复。
