外部lib
add_library(baz STATIC IMPORTED)
set_target_properties(baz PROPERTIES
IMPORTED_LOCATION_RELEASE ${CMAKE_CURRENT_SOURCE_DIR}/libbaz.a
IMPORTED_LOCATION_DEBUG ${CMAKE_CURRENT_SOURCE_DIR}/libbazd.a)
add_library(bar STATIC IMPORTED)
set_target_properties(bar PROPERTIES
IMPORTED_LOCATION_RELEASE ${CMAKE_CURRENT_SOURCE_DIR}/libbar.a
IMPORTED_LOCATION_DEBUG ${CMAKE_CURRENT_SOURCE_DIR}/libbard.a
IMPORTED_LINK_INTERFACE_LIBRARIES baz) # <-- dependency is here
注意动态库和静态库稍有区别：
add_library(bar SHARED IMPORTED)
set_property(TARGET bar PROPERTY IMPORTED_LOCATION c:/path/to/bar.dll)
set_property(TARGET bar PROPERTY IMPORTED_IMPLIB c:/path/to/bar.lib)
add_executable(myexe src1.c src2.c)
target_link_libraries(myexe bar)
内部lib直接写target name就OK，但是必须在同一个proj下
还有一种方式
TARGET_LINK_LIBRARIES(skiaSampleCode
debug skiaCored.lib
optimized skiaCore.lib)
PROJECT_SOURCE_DIR CMAKE_CURRENT_SOURCE_DIR CMAKE_SOURCE_DIR 注意这三者的区别
