Catkin - files are not found after install. Wrong directories?

edit

Unfortunately, the default CMake install location is /usr/local, not a good destination for ROS packages. So, you need to configure your catkin workspace, somewhat like this example:

$ cd ~/catkin_ws/build
$ cmake ../src -DCMAKE_INSTALL_PREFIX=../install

Then, you need to add CMake install() commands to your CMakeLists.txt.

For example, if you need to install C++ headers where they can be found by other packages:

install(DIRECTORY include/
   DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
)

Similarly, if there is a shared libraries needed by other packages at runtime:

install(
  TARGETS your_shared_library
  LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
)

Note that catkin library names have system-wide scope, so make sure they clearly describe their role. Include names are less of an issue, since they are usually in a subdirectory under your package name.
