前述

这里整一个cmake引入三方库及导出安装包的示例代码。
引入三方库用的是

set(*_DIR "**")
find_package(*)
target_link_libraries(${PROJECT_NAME} PRIVATE *)

导出安装报用到的是

install(TARGETS ${PROJECT_NAME} 
    RUNTIME 
    DESTINATION bin
)

install(
    FILES
    $<TARGET_FILE:*>
    DESTINATION bin
)
include (InstallRequiredSystemLibraries)\
...此处为CPack配置...
include(CPack)

示例

test.zip
Git testMain
Git testLib

代码

部分代码已注释，具体详解也写道对应的注释里了。
