Could not find a package configuration file provided by "catkin_simple"

 By not providing "Findcatkin_simple.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "catkin_simple", but CMake did not find one.

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

    catkin_simpleConfig.cmake
    catkin_simple-config.cmake

  Add the installation prefix of "catkin_simple" to CMAKE_PREFIX_PATH or set
  "catkin_simple_DIR" to a directory containing one of the above files.  If
  "catkin_simple" provides a separate development package or SDK, be sure it
  has been installed.

 

在该工程目录下打开终端，输入

git clone https://github.com/catkin/catkin_simple

将catkin_simple 包下载下来，在CMakeList.txt里面加上一句：

add_subdirectory(catkin_simple)

就可以cmake通过了。
