Dependancy Problem Packaging c library

edit

Hey there. Unfortunately I have another problem: With the dependencies in the Cmakelist:

cmake_minimum_required(VERSION 2.8)
project(grampc)

find_package(catkin REQUIRED COMPONENTS roscpp rospy std_msgs message_runtime rosbag)

add_service_files(FILES grampc_IO.srv)
generate_messages(DEPENDENCIES std_msgs)

catkin_package(
  CATKIN_DEPENDS roscpp rospy std_msgs message_runtime message_generation rosbag
)

include_directories(
  include ${catkin_INCLUDE_DIRS}
)

# define libgrampc sources
set(
  grampc_SRCS

  src/euler1.c
  src/eulermod2.c
  src/grampc_init.c
  src/grampc_mess.c
  src/grampc_run.c
  src/grampc_setopt.c
  src/grampc_setparam.c
  src/heun2.c
  src/probfct.c
  src/ruku45.c
)

# define a libgrampc target
add_library(grampc ${grampc_SRCS})

# define a grampc_node target
add_executable(grampc_node src/grampc.cpp)

# now link our node to the library, and all the libraries from the other pkgs
target_link_libraries(grampc_node grampc ${catkin_LIBRARIES})

add_dependencies(grampc_node grampc_gencpp)

When I execute: catkin_make grampc, than the pkg compiles:

####
#### Running command: "make grampc -j4 -l4" in "/home/dentler/Workspace/catkin/build"
####
[100%] Built target grampc

But when I build the whole workspace with catkin_make I have the same issue like before?!
