一个 CMake 项目创建两个 Debian 包

Question

我有一个看起来像这样的 CMake 项目：

-Project
|--ApplicationA
|     |---main.cpp
|     |---CMakeLists.txt
|--ApplicationB
|     |---main.cpp
|     |---CMakeLists.txt
|--CMakeLists.txt

有没有可能我可以运行 "make packages" (CPack) 并且它会为 ApplicationA 创建一个 Debian 软件包，为 ApplicationB 创建一个？

Answer 1

您可以为安装命令指定组件。 CMake Components

Answer 2

我也在研究这个，但是很难找到信息，所以对于正在寻找这种解决方案的其他人来说，这就是我使用组件完成的方法，也是一个主要CMakeLists.txt 和子目录中的另外两个 CMakeLists.txt。对于这些 Debian 软件包，它只是为了获得正确的依赖关系（因此没有要构建的特定 cpp 文件）。

对于我的解决方案，这是主目录中 CMakeLists.txt 的内容：

cmake_minimum_required(VERSION 3.7.2)

project(EVSE-PACKAGE-GENERATOR VERSION 3.0.0)

set(CPACK_COMPONENTS_ALL <COMPONENT_1> <COMPONENT_2>)
set(CPACK_GENERATOR "DEB")
set(CPACK_DEBIAN_PACKAGE_MAINTAINER "Maintainer")
set(CPACK_DEB_COMPONENT_INSTALL ON)
set(CPACK_DEBIAN_PACKAGE_ARCHITECTURE "...")

add_subdirectory(subdirectory1) #In this case "ApplicationA"

add_subdirectory(subdirectory2) #In this case "ApplicationB"

include(CPack)

组件 1 (ApplicationA) 的 CMakeLists.txt：

cmake_minimum_required(VERSION a.b.c)

project(<COMPONENT_1> VERSION x.y.z)

set(CPACK_COMPONENT_<COMPONENT_1>_DESCRIPTION "Component 1 description" PARENT_SCOPE)
set(CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_FILE_NAME "comp1name")
set(CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_NAME "prefix-${CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_FILE_NAME}" PARENT_SCOPE)
set(CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_DEPENDS "..." PARENT_SCOPE)

set(CPACK_<COMPONENT_1>_PACKAGE_VERSION "${PROJECT_VERSION}${PROJECT_VERSION_PRERELEASE}")
set(CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_ARCHITECTURE "...")

string(TOLOWER "prefix-${CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_FILE_NAME}_${CPACK_<COMPONENT_1>_PACKAGE_VERSION}_${CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_ARCHITECTURE}.deb" DEBIAN_<COMPONENT_1>_FILENAME_STRING )
set(CPACK_DEBIAN_<COMPONENT_1>_FILE_NAME ${DEBIAN_<COMPONENT_1>_FILENAME_STRING} PARENT_SCOPE )
set(CPACK_DEBIAN_<COMPONENT_1>_PACKAGE_CONTROL_STRICT_PERMISSION TRUE PARENT_SCOPE)

和组件 2（应用程序 B）：

cmake_minimum_required(VERSION a.b.c)

project(<COMPONENT_2> VERSION x.y.z)

set(CPACK_COMPONENT_<COMPONENT_2>_DESCRIPTION "Component 2 description" PARENT_SCOPE)
set(CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_FILE_NAME "comp2name")
set(CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_NAME "prefix-${CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_FILE_NAME}" PARENT_SCOPE)
set(CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_DEPENDS "..." PARENT_SCOPE)

set(CPACK_<COMPONENT_2>_PACKAGE_VERSION "${PROJECT_VERSION}${PROJECT_VERSION_PRERELEASE}" )
set(CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_ARCHITECTURE "..." )

string(TOLOWER "prefix-${CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_FILE_NAME}_${CPACK_<COMPONENT_2>_PACKAGE_VERSION}_${CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_ARCHITECTURE}.deb" DEBIAN_<COMPONENT_2>_FILENAME_STRING )
set(CPACK_DEBIAN_<COMPONENT_2>_FILE_NAME ${DEBIAN_<COMPONENT_2>_FILENAME_STRING} PARENT_SCOPE )
set(CPACK_DEBIAN_<COMPONENT_2>_PACKAGE_CONTROL_STRICT_PERMISSION_PACKAGE_CONTROL_STRICT_PERMISSION TRUE PARENT_SCOPE)
