cmake - cpack 组件级安装

Question

对于附加到 CMake wiki 的示例 CMakeLists.txt。我还在下面添加了实际的 make 命令来创建基于组件的 TGZ。我很困惑，在文档中没有看到任何帮助。

CMakeLists.txt

cmake_minimum_required(VERSION 2.6.0 FATAL_ERROR)
project(MyLib)

if(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)
    set(CMAKE_INSTALL_PREFIX "/usr" CACHE PATH "Install path prefix prepended on to install directories." FORCE)
endif(CMAKE_INSTALL_PREFIX_INITIALIZED_TO_DEFAULT)

set(CPACK_PACKAGE_NAME "MyLib")
set(CPACK_PACKAGE_VENDOR "CMake.org")
set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "MyLib - CPack Component Installation Example")
set(CPACK_PACKAGE_VERSION "1.0.0")
set(CPACK_PACKAGE_VERSION_MAJOR "1")
set(CPACK_PACKAGE_VERSION_MINOR "0")
set(CPACK_PACKAGE_VERSION_PATCH "0")
set(CPACK_PACKAGE_INSTALL_DIRECTORY "CPack Component Example")


add_library(mylib mylib.cpp)

add_executable(mylibapp mylibapp.cpp)
target_link_libraries(mylibapp mylib)

install(TARGETS mylib 
   ARCHIVE
   DESTINATION lib
   COMPONENT libraries)
install(TARGETS mylibapp
   RUNTIME
   DESTINATION bin
   COMPONENT applications)
install(FILES mylib.h
   DESTINATION include
   COMPONENT headers)

set(CPACK_COMPONENTS_ALL applications libraries headers)

set(CPACK_COMPONENT_APPLICATIONS_DISPLAY_NAME "MyLib Application")
set(CPACK_COMPONENT_LIBRARIES_DISPLAY_NAME "Libraries")
set(CPACK_COMPONENT_HEADERS_DISPLAY_NAME "C++ Headers")

set(CPACK_COMPONENT_APPLICATIONS_DESCRIPTION 
   "An extremely useful application that makes use of MyLib")
set(CPACK_COMPONENT_LIBRARIES_DESCRIPTION
   "Static libraries used to build programs with MyLib")
set(CPACK_COMPONENT_HEADERS_DESCRIPTION
   "C/C++ header files for use with MyLib")


set(CPACK_GENERATOR "TGZ")
set(CPACK_ARCHIVE_COMPONENT_INSTALL ON)
set(CPACK_INCLUDE_TOPLEVEL_DIRECTORY OFF)
set(CPACK_COMPONENT_INCLUDE_TOPLEVEL_DIRECTORY OFF)
set(CPACK_SET_DESTDIR ON)
set(CPACK_PACKAGE_CONTACT "jhf")

# This must always be last!
include(CPack)

我有一个类似的 CMakeLists.txt，当我这样做时 make package ，我最终在 TGZ 中获得了我所有的二进制文件和库。如果我只需要一个带有上述 CMakeLists.txt 应用程序组件的 TGZ，那么 make package 命令应该是什么？

很简单。
只需将 CMAKE 变量 CPACK_COMPONENTS_ALL 设置为要出现在安装中的组件列表:

SET(CPACK_COMPONENTS_ALL applications) #only pack "applications" component
