我的项目结构如下：

utils 
 include
   utils 
    image_utils.h
 CMakelists.txt
 package.xml
graph
 src
  graph.cpp
 CMakelists.txt
 package.xml

我正在尝试在graph.cpp中使用image_utils.h。
utils内部的CMakelists如下所示：

cmake_minimum_required(VERSION 3.0.2)
project(utils)

find_package(catkin REQUIRED COMPONENTS roscpp)
catkin_package(
  INCLUDE_DIRS include
  LIBRARIES ${PROJECT_NAME}
  CATKIN_DEPENDS roscpp 
)
include_directories(
  include
  ${catkin_INCLUDE_DIRS}
)

add_library(${PROJECT_NAME} INTERFACE)
target_link_libraries(${PROJECT_NAME} INTERFACE ${catkin_LIBRARIES} )

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

在CMakelists内部图中，我调用find_package(catkin REQUIRED COMPONENTS roscpp)，如下所示：

cmake_minimum_required(VERSION 3.0.2)
project(pose_graph)

set(CMAKE_BUILD_TYPE "Release")
set(CMAKE_CXX_FLAGS "-std=c++11")

find_package(catkin REQUIRED COMPONENTS roscpp std_msgs cv_bridge utils)

find_package(OpenCV 3.4 REQUIRED)

include_directories(${catkin_INCLUDE_DIRS} )
catkin_package(CATKIN_DEPENDS utils)
add_executable(graph src/graph.cpp)
target_link_libraries(graph ${catkin_LIBRARIES} ${OpenCV_LIBS} utils)

图形的package.xml具有以下相关标记：

<depend>utils</depend>

我的错误消息是：

graph.cpp:12:10: fatal error: utils/image_utils.h: No such file or directory
 #include "utils/image_utils.h"
          ^~~~~~~~~~~~~~~~~~~~~

你知道我做错了什么吗？
