CPack 具有自己依赖项的多个包

Question

我在使用 CPack 和 CMake 创建两个 debian 软件包时遇到了问题。我已经完成了 here 中的示例，并且我确实设法创建了两个不同的 debian 软件包，但我希望它们每个都有自己的依赖项。结果 CMakeLists.txt 如下：

cmake_minimum_required(VERSION 2.8.0)
project(MyLib)

add_library(mylib mylib.cpp)

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

install(TARGETS mylib 
  ARCHIVE
  DESTINATION ~/Downloads/ComponentExampleStart/lib
  COMPONENT libraries)

install(TARGETS mylibapp
  RUNTIME
  DESTINATION ~/Downloads/ComponentExampleStart/bin
  COMPONENT applications)

install(FILES mylib.h
  DESTINATION ~/Downloads/ComponentExampleStart/include
  COMPONENT headers)

file(WRITE dummy_main1.c "int main(int argc, char** argv){return 0;}")
add_executable(dummy_main1 dummy_main1.c)
INSTALL (FILES ${CMAKE_CURRENT_SOURCE_DIR}/dummy_main1 DESTINATION /tmp COMPONENT headers OPTIONAL PERMISSIONS OWNER_EXECUTE GROUP_EXECUTE WORLD_EXECUTE)

file(WRITE dummy_main2.c "int main(int argc, char** argv){return 0;}")
add_executable(dummy_main2 dummy_main2.c)
INSTALL (FILES ${CMAKE_CURRENT_SOURCE_DIR}/dummy_main2 DESTINATION /tmp COMPONENT mylibapp OPTIONAL PERMISSIONS OWNER_EXECUTE GROUP_EXECUTE WORLD_EXECUTE )

SET (CPACK_GENERATOR "DEB")
SET (CPACK_SOURCE_GENERATOR TGZ)
SET (CPACK_DEBIAN_PACKAGE_SHLIBDEPS ON)
SET (CPACK_SET_DESTDIR "on")
set(CPACK_DEB_COMPONENT_INSTALL ON)
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")
set(CPACK_COMPONENTS_ALL applications libraries headers)
set(CPACK_COMPONENT_APPLICATIONS_GROUP "Runtime")
set(CPACK_COMPONENT_LIBRARIES_GROUP "Development")
set(CPACK_COMPONENT_HEADERS_GROUP "Development")
set(CPACK_COMPONENT_LIBRARIES_DEPENDS "libxml2")
set(CPACK_COMPONENT_HEADERS_DEPENDS "libxml2")

set(CPACK_DEBIAN_PACKAGE_DEPENDS "libusb-1.0-0")
SET (CPACK_PACKAGE_CONTACT "Example ")
SET (CPACK_PACKAGE_FILE_NAME "${CMAKE_PROJECT_NAME}_${VERSION}_${CPACK_DEBIAN_PACKAGE_ARCHITECTURE}")

include(CPack)

(注意 dummy_main1 和 dummy_main2 使 shlibdeps 工作，因为每个包至少需要一个可执行文件。

我的 objective 是创建 2 个具有不同依赖关系的不同 debian 软件包，例如：

MyLib_1.0.0_amd64-Developers.deb --- depends on ---> libxml2
MyLib_1.0.0_amd64-Runtime.deb --- depends on ---> lubusb-1.0-0

但我找不到执行此操作的 CPACK 宏。我阅读了很多论坛和文档，但 none 我测试过的内容对我有用。 CPACK_DEBIAN_PACKAGE_DEPENDS 宏工作正常，但它为两个包设置了相同的依赖关系。有什么办法可以实现我的目标吗？我正在使用 CMake 2.8 来执行此操作。

谢谢！

Answer 1

好吧，我终于设法隔离了依赖关系。问题是我使用的 CMake 版本 (2.8)。这可以在最新版本（当前使用 3.3）中使用 CPack 宏完成：CPACK_DEBIAN__PACKAGE_DEPENDS

CPack 具有自己依赖项的多个包

CPack multiple packages with own dependencies

c++

linux

packages

cmake

cpack
