CmakeList.txt修改时的注意事项

来源：互联网发布：知乎编程电脑配置要求编辑：程序博客网时间：2024/05/19 12:11

CMakeLists.txt修改添加生成文件或信息功能，添加依赖文件或ROS包功能等时，请遵从函数顺序，否则，会导致在工作空间的catkin_make失败。

举个文件

cmake_minimum_required(VERSION 2.8.3)
project(leaning_actionlib)

## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS
actionlib
actionlib_msgs
message_generation
roscpp
rospy
std_msgs
)

add_action_files(
DIRECTORY action
FILES Fibonacci.action
)

generate_messages(
DEPENDENCIES actionlib_msgs std_msgs # Or other packages containing msgs
)

catkin_package(
# INCLUDE_DIRS include
# LIBRARIES leaning_actionlib
# CATKIN_DEPENDS actionlib actionlib_msgs message_generation roscpp rospy std_msgs
# DEPENDS system_lib
CATKIN_DEPENDS actionlib_msgs
)

###########
## Build ##
###########

## Specify additional locations of header files
## Your package locations should be listed before other locations
# include_directories(include)
include_directories(
${catkin_INCLUDE_DIRS}
)

以上有颜色的是要遵循一定顺序排放的，就好像要先开roscore才能用roslaunch一样。+
