Catkinising package- Unable to include a header file from another package- Indigo

edit

I have three packages in the same workspace called:

art_msgs (contains messages in art_msgs/msg folder)

art_common (contains some nodes in art_common/srcfolder which depend on messages from art_msgs; and art_common/include/art folder)

art_map (contains nodes in art_map/src which depend on art_common)

I am able to successfully compile art_msgs and art_common. However the nodes of art_map include header files from art_common/include/art which are not included when I catkin_build the workspace.

Based on another post, I have tried installing the header file, by adding the following in CMakeLists.txt of art_common

install(DIRECTORY include/art/
  DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
  FILES_MATCHING PATTERN "*.h"
PATTERN ".svn" EXCLUDE)

which results in the following error:

In file included from /home/amogh/rosws2/src/art_map/src/DrawLanes.cc:2:0:
/home/amogh/rosws2/src/art_map/include/art_map/euclidean_distance.h:20:25: fatal error: art/epsilon.h: No such file or directory
 #include <art/epsilon.h>

Also when I add the following, in CMakeLists.txt of art_map:

find_package(catkin REQUIRED COMPONENTS art_common)

The following error arises:

Errors     << art_map:check /home/amogh/rosws2/logs/art_map/build.check.044.log                          
CMake Error at /home/amogh/rosws2/devel/share/art_common/cmake/art_commonConfig.cmake:165 (find_package):
  By not providing "Findart_msgs.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "art_msgs",
  but CMake did not find one.

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

    art_msgsConfig.cmake
    art_msgs-config.cmake

Other required dependencies have been resolved in package.xml and CMakeLists.txt. You can see the complete code here.
