Hi,

I am trying to compile the package of Prius self driving-car in my ws (Ros kinetic 16.04) from https://github.com/osrf/car_demo I am having the following issue:

CMake Error at car_demo-master/car_demo/CMakeLists.txt:15 (find_package):
  By not providing "Findignition-msgs1.cmake" in CMAKE_MODULE_PATH this
  project has asked CMake to find a package configuration file provided by
  "ignition-msgs1", but CMake did not find one.

  Could not find a package configuration file provided by "ignition-msgs1"
  with any of the following names:

    ignition-msgs1Config.cmake
    ignition-msgs1-config.cmake

  Add the installation prefix of "ignition-msgs1" to CMAKE_PREFIX_PATH or set
  "ignition-msgs1_DIR" to a directory containing one of the above files.  If
  "ignition-msgs1" provides a separate development package or SDK, be sure it
  has been installed.

My CmakeList is below ( I have already changed one line which required gazebo 9 to gazebo 7 to correct another issue)

install(DIRECTORY models DESTINATION ${CATKIN_PACKAGE_SHARE_DESTINATION})

I tried to install the ignition-msgs1 through the command "sudo apt-get install ro-kinetic-libigntion... but just appear to me the ignition-transport0 and math2 options, not the igntion-msg1 as required... So what should I do to fix this error?
