如何根据配置更改CPack包文件名？

Question

在 CMake 中，使用 CPack 我想CPACK_PACKAGE_FILE_NAME包含-debug后缀，以防包是从调试配置生成的。对于单配置 CMake 生成器，这可能可以通过检查来实现CMAKE_BUILD_TYPE，但这不适用于 Visual Studio 等多配置生成器。

add_custom_target我已经通过+ expression generator+做到了standalone cmake script for the cpack：

CMakeLists.txt

...

set(CPACK_PACKAGE_VERSION "1.0.0.0")
set(CPACK_MONOLITHIC_INSTALL 1)
set(CPACK_OUTPUT_CONFIG_FILE "${CMAKE_BINARY_DIR}/BundleConfig.cmake")

include(CPack)

set(CPACK_BUNDLE_TEMPLATE_CONFIG_FILE "${CMAKE_BINARY_DIR}/CPackConfig.cmake.in")
set(CPACK_BUNDLE_OUTPUT_CONFIG_FILE "${CMAKE_BINARY_DIR}/CPackProperties.cmake")

# make cpack configuration template for later replacements with the expression generator support
file(WRITE "${CPACK_BUNDLE_TEMPLATE_CONFIG_FILE}" "")
file(APPEND "${CPACK_BUNDLE_TEMPLATE_CONFIG_FILE}" "set(CPACK_PACKAGE_FILE_NAME \"\${CPACK_PACKAGE_FILE_NAME}\")\n")

add_custom_target(bundle
  COMMAND ${CMAKE_COMMAND}
    # this one must be written as is, DO NOT put the `$<CONFIGURATION>` inside a variable!
    -D "CPACK_PACKAGE_FILE_NAME=${PROJECT_NAME}-${CPACK_PACKAGE_VERSION}-win32-$<CONFIGURATION>"
    -D "CPACK_BUNDLE_TEMPLATE_CONFIG_FILE=${CPACK_BUNDLE_TEMPLATE_CONFIG_FILE}"
    -D "CPACK_BUNDLE_OUTPUT_CONFIG_FILE=${CPACK_BUNDLE_OUTPUT_CONFIG_FILE}"
    # this one must be after all `-D`s
    -P "${CMAKE_CURRENT_LIST_DIR}/CPackMakeConfig.cmake"
  COMMAND "${CMAKE_CPACK_COMMAND}" 
    "-G" "NSIS"
    "-C" "$<CONFIGURATION>"
    "--config" "${CPACK_OUTPUT_CONFIG_FILE}")

CPackMakeConfig.cmake

if (NOT CPACK_BUNDLE_TEMPLATE_CONFIG_FILE)
  message(FATAL_ERROR "* CPACK_BUNDLE_TEMPLATE_CONFIG_FILE variable must be defined!")
endif()
if (NOT CPACK_BUNDLE_OUTPUT_CONFIG_FILE)
  message(FATAL_ERROR "* CPACK_BUNDLE_OUTPUT_CONFIG_FILE variable must be defined!")
endif()

CONFIGURE_FILE("${CPACK_BUNDLE_TEMPLATE_CONFIG_FILE}" "${CPACK_BUNDLE_OUTPUT_CONFIG_FILE}")

因为配置脚本的末尾cpack会自动包含该脚本，所以您只需在执行之前的 cmake 构建阶段（目标）将实际值写入其中即可。CPackProperties.cmakeBundleConfig.cmakeBUNDLEcpack

cmake --build . --config Debug --target BUNDLE
