Hi, I got an issue while building the package:

Could not find a package configuration file provided by "g2o" with any of
  the following names:

    g2oConfig.cmake
    g2o-config.cmake

After I installed the g2o lib(https://github.com/RainerKuemmerle/g2o), and try to build again, it then reports:

Starting >>> scanmatcher
--- stderr: graph_based_slam                                                                    
** WARNING ** io features related to pcap will be disabled
CMake Error at /usr/local/lib/cmake/g2o/modules/FindSuiteSparse.cmake:182 (message):

  component).

  /usr/local/lib/cmake/g2o/g2oConfig.cmake:7 (find_dependency)
  CMakeLists.txt:38 (find_package)

What could be the reason for this error?

[update]
using rosdep solved the problem.

sudo rosdep init
rosdep update

and then

rosdep install --from-paths src -y --ignore-src

Thanks for the report, I've added the rosdep command to the readme.md.
The issue seems to be resolved, so I will cloze this issue.
