Linker errors when linking ros libraries because of missing link_directores #277

Original comment by Lorenz Mösenlechner (Bitbucket: moesenle). I'm not sure. I don't think the evaluation order of subdirectories is defined in CMake anywhere so I don't think it's a bug in CMake. My guess what happens on your system is that the subdirectory gazebo/sdf/interface is expanded first while it is expanded later on my system. I think cmake is just not deterministic there. Btw. I get the same issue with CMake 2.8.7, too. I've seen it on at least three different computers. |

Original comment by Lorenz Mösenlechner (Bitbucket: moesenle). John, is maybe urdfdom and console_bridge not installed on your system? In that case you wouldn't run into the error since libgazebo_sdf_interface would not link against them. I have ros groovy installed which provides the two libraries. |

Original report (archived issue) by Lorenz Mösenlechner (Bitbucket: moesenle).
The original report had attachments: gazebo-cmake-link-directories.patch
When compiling gazebo (current tip as of Dec. 5) I ran into a bunch of linker errors because the build could not find the urdfdom and console_bridge libraries. The problem seems to be that with my cmake version (2.8.10.2), targets get added before /opt/ros/groovy/lib is added with link_directories. Adding ${urdfdom_LIBRARY_DIRS} and friends in gazebo, plugins and tests before processing all subdirectories solves the issue. Patch attached.
