cmake 强制链接静态库

add_executable(main main.cpp)
target_link_libraries(main ${CMAKE_SOURCE_DIR}/libbingitup.a)

静态库和动态库共存时，cmake会默认先链接静态库，如果要强制使用静态库，在CMakeLists.txt中如此直接指明

或者这样做也可以

So, if you want to link to a static library, you need to search for that static library:

find_library(SOMELIB libsomelib.a)
instead of:

find_library(SOMELIB somelib)
