cmake报错：The keyword signature for target_link_libraries has already been used with
  the target "main".  All uses of target_link_libraries with a target must be
  either all-keyword or all-plain.


解决：将target_link_libraries函数中的<INTERFACE|PUBLIC|PRIVATE>删掉
# target_link_libraries(main INTERFACE "/usr/local/include/kfr/")
target_link_libraries(main "/usr/local/include/kfr/")
