如何用一个构建制作两个不同的 RPM？

Question

目前，我正在使用以下 CMakeLists.txt 文件构建一个名为 firstrpm 的 RPM。我将规范文件扩展为具有 %package 指令的子包，现在我想扩展 CMakeLists 以制作两个 rpm（比如 firstrpm 和 secondrpm）。我怎样才能扩展它以使第二个 RPM 也具有不同的包名称，使用单个构建？

set(CPACK_PACKAGE_RELEASE_VERSION ${PROJECT_VERSION_RELEASE})
set(CPACK_PACKAGE_MINOR_VERSION ${PROJECT_VERSION_MINOR})
set(CPACK_PACKAGE_SERVICE_PACK ${PROJECT_VERSION_SERVICE_PACK})
set(CPACK_PACKAGE_BUILD ${PROJECT_VERSION_BUILD})
set(CPACK_SPEC_FILE_DIR ${CMAKE_CURRENT_BINARY_DIR})    
set(CPACK_GENERATOR "RPM")
set(CPACK_PACKAGE_NAME "firstrpm")
set(CPACK_PACKAGING_INSTALL_PREFIX ${CMAKE_CURRENT_BINARY_DIR})
set(CPACK_PACKAGE_FILE_NAME "${CPACK_PACKAGE_NAME}-${CPACK_PACKAGE_RELEASE_VERSION}.${CPACK_PACKAGE_MINOR_VERSION}.${CPACK_PACKAGE_SERVICE_PACK}-${CPACK_PACKAGE_BUILD}.${CMAKE_SYSTEM_PROCESSOR}")

configure_file("${CMAKE_CURRENT_SOURCE_DIR}/${CPACK_PACKAGE_NAME}.spec.in" "${CPACK_SPEC_FILE_DIR}/${CPACK_PACKAGE_NAME}.spec" @ONLY IMMEDIATE)
configure_file("${CMAKE_CURRENT_SOURCE_DIR}/${CPACK_PACKAGE_NAME}-devel.spec.in" "${CPACK_SPEC_FILE_DIR}/${CPACK_PACKAGE_NAME}-devel.spec" @ONLY IMMEDIATE)
set(CPACK_RPM_USER_BINARY_SPECFILE "${CPACK_SPEC_FILE_DIR}/${CPACK_PACKAGE_NAME}.spec")

set(CPACK_TEMPORARY_PACKAGE_FILE_NAME "${CMAKE_BINARY_DIR}/_CPack_Packages/Linux/RPM/RPMS/${CMAKE_SYSTEM_PROCESSOR}/${CPACK_PACKAGE_FILE_NAME}.rpm")
include(CPack)

来自一个源包的第二个二进制包称为“子包”。您只需在规范文件（或 spec.in）中添加几行。见：

而且您不需要手动创建 -devel 子包。除非您指定“BuildArch: noarch”，否则它将自动创建。
