Issues with packages recognizing external header files

edit

So I am currently trying to get a given catkin package(description) to recognize header files stored in another catkin package(cat_ball). However, when I attempt to run catkin_make I get this error

fatal error: simulation/ControllerSimulator.h: No such file or directory
compilation terminated.

(Note: simulation/ControllerSimulator.h does exist in cat_ball/include)

Below is the CMakeLists.txt file and yes I have made sure that description is both run_dependent and build_dependent on cat_ball in the package.xml and that cat_ball is also a catkin package.

   cmake_minimum_required(VERSION 2.8.3)
project(description)

find_package(catkin REQUIRED COMPONENTS roscpp gazebo_ros cat_ball)

# Find gazebo
include (FindPkgConfig)
if (PKG_CONFIG_FOUND)
  pkg_check_modules(GAZEBO gazebo)
endif()

link_directories(${GAZEBO_LIBRARY_DIRS})
include_directories(include ${Boost_INCLUDE_DIRS} ${catkin_INCLUDE_DIRS} ${GAZEBO_INCLUDE_DIRS})

add_library(${PROJECT_NAME} src/plugin.cpp)
target_link_libraries(${PROJECT_NAME} ${catkin_LIBRARIES})

catkin_package(DEPENDS roscpp gazebo_ros CATKIN_DEPENDS cat_ball)

If anyone could help me with this problem I would be very grateful, thanks.
