CPack打包外部库

要使用CPack打包外部库，需要按照以下步骤操作：

1.在CMakeLists.txt文件中定义要打包的目标，包括库文件和头文件。例如：

add_library(mylib SHARED mylib.cpp)
target_include_directories(mylib PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/include)

2.在CMakeLists.txt文件中添加CPack相关设置。例如：

set(CPACK_GENERATOR "ZIP")
set(CPACK_PACKAGE_NAME "mylib")
set(CPACK_PACKAGE_VERSION "1.0.0")
set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "My library")
set(CPACK_PACKAGE_VENDOR "My Company")
set(CPACK_PACKAGE_FILE_NAME "${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}")
set(CPACK_RESOURCE_FILE_LICENSE "${CMAKE_CURRENT_SOURCE_DIR}/LICENSE")
set(CPACK_SOURCE_PACKAGE_FILE_NAME "${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_VERSION}-src")
set(CPACK_SOURCE_GENERATOR "ZIP")
set(CPACK_SOURCE_IGNORE_FILES
    "/build/"
    "/.git/"
    "/.idea/"
    "/tmp/"
    "/dist/"
)
include(CPack)

其中，`CPACK_GENERATOR`设置打包格式，`CPACK_PACKAGE_NAME`设置包名，`CPACK_PACKAGE_VERSION`设置版本号，`CPACK_PACKAGE_DESCRIPTION_SUMMARY`设置简介，`CPACK_PACKAGE_VENDOR`设置厂商，`CPACK_PACKAGE_FILE_NAME`设置生成包的文件名，`CPACK_SOURCE_PACKAGE_FILE_NAME`设置源代码包的文件名，`CPACK_RESOURCE_FILE_LICENSE`设置许可证文件路径，`CPACK_SOURCE_IGNORE_FILES`设置忽略的文件。

3.使用`cpack`命令生成打包文件。例如：

$ mkdir build
$ cd build
$ cmake ..
$ make
$ cpack --config CPackConfig.cmake

生成的打包文件会在build目录下生成。
