catkin build说明

与catkin_make不同，可以参考catkin build – Build Packages中文翻译版手册
catkin build 默认会生成.private文件夹。链接时候可能出现失败的问题。catkin参数配置之软连接模式
改为如下模式即可

catkin init
catkin config --merge-devel
catkin build

Bug

Issue1: 引用工作空间下别的包的lib报错

参考CmakeLists.txt import and export官方文档
假设ov_core需要被ov_msckf调用，一般情况ov_core需要export他自身。

ov_core的CmakeLists

这里提供一个补救小技巧，当前面没有进行正常的install操作，但是ov_msckf包依旧想链接super_point_glue_lib时，可以手动指定这个包的位置。一般情况下，如果像ov_core那样正常export和install，那么ov_msckf就可以找到。

# wzy import this lib
# add_library(super_point_glue_lib SHARED IMPORTED)
# set_property(TARGET super_point_glue_lib PROPERTY
#              IMPORTED_LOCATION "/home/zph/vins_ws/devel/lib/libsuper_point_glue_lib.so")
# target_link_libraries(ov_msckf_lib super_point_glue_lib yaml-cpp ${thirdparty_libraries}) # wzy change
