CMake Error at /home/sany/WorkSpace/test_ws/devel/share/A/cmake/AConfig.cmake:173 (message): Project ‘B‘ tried to find library ‘A‘. The library is neither a target nor built/installed properly. Did you compile project ‘A‘? Did you find_package() it before the subdirectory containing its code is included? Call Stack (most recent call first): /opt/ros/noetic/share/catkin/cmake/catkinConfig.cmake:76 (find_package) B/CMakeLists.txt:10 (find_package)
在编译的时候遇到上述错误，复现方法如下：
1. 创建ros的A包：
catkin_create_pkg A rospy roscpp
修改 A包的CMakeLists.txt，表示A包提供头文件INCLUDE_DIRS和LIBRARIES A给其他包依赖。
catkin_package(
INCLUDE_DIRS include
LIBRARIES A
# CATKIN_DEPENDS geometry_msgs nav_msgs roscpp rospy std_msgs task_manager tf2
# DEPENDS system_lib
)
2. 创建ros的B包：
catkin_create_pkg B rospy roscpp A
3. catkin_make，即得到上述错误。
原因分析：
A包输出了并不存在的库（LIBRARIES A)，导致B包find_package()在寻找A库的时候无法找到。
当去掉LIBRARIES A的时候，find_package（）将不会寻找LIBRARIES A，因此CMAKE配置通过。
