如何通过CMake将所有输出（含中间文件）放入Release子文件夹？

我在Windows平台使用的CMakeLists.txt内容如下：

cmake_minimum_required(VERSION 3.5)

project(LogMsg)

# Set the project source files
set(SOURCES
    LogMsg.cpp
    LogMsgMain.rc
    LogMsg.h
    resource.h
    stdafx.h
)

# Add executable target
add_library(LogMsg SHARED ${SOURCES})

# Set the configuration-specific outputs
set_target_properties(LogMsg PROPERTIES
    RUNTIME_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_SOURCE_DIR}/Debug"
    RUNTIME_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_SOURCE_DIR}/Release"
)

# Add include directories
target_include_directories(LogMsg PRIVATE ${CMAKE_CURRENT_SOURCE_DIR})

# Specify custom build commands
add_custom_command(TARGET LogMsg POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy_if_different "${CMAKE_CURRENT_SOURCE_DIR}/LogMsg.rc" "$<TARGET_FILE_DIR:LogMsg>"
    COMMAND ${CMAKE_COMMAND} -E copy_if_different "${CMAKE_CURRENT_SOURCE_DIR}/LogMsg.h" "$<TARGET_FILE_DIR:LogMsg>"
)

执行的命令：

cmake -G "Visual Studio 17 2022" -S . -B .
cmake --build . --config Release

目前Release子文件夹中生成了.dll文件、.rc文件和.h文件，但LogMsg.tlog目录以及LogMsg.dll.recipe、LogMsg.obj、LogMsgMain.res等中间文件生成在LogMsg.dir/Release路径下，希望将这些文件也直接放入Release文件夹，请问该如何配置？

只需在set_target_properties中添加配置特定的中间文件输出目录属性，就能把.obj、.res、.recipe及tlog目录等中间文件直接生成到Debug/Release文件夹中。

修改后的CMakeLists.txt如下：

cmake_minimum_required(VERSION 3.5)

project(LogMsg)

# Set the project source files
set(SOURCES
    LogMsg.cpp
    LogMsgMain.rc
    LogMsg.h
    resource.h
    stdafx.h
)

# Add executable target
add_library(LogMsg SHARED ${SOURCES})

# Set configuration-specific output directories for runtime and intermediate files
set_target_properties(LogMsg PROPERTIES
    # 指定运行时文件（如dll）的输出目录
    RUNTIME_OUTPUT_DIRECTORY_DEBUG "${CMAKE_CURRENT_SOURCE_DIR}/Debug"
    RUNTIME_OUTPUT_DIRECTORY_RELEASE "${CMAKE_CURRENT_SOURCE_DIR}/Release"
    # 指定中间编译文件的输出目录
    INTERMEDIATE_DIRECTORY_DEBUG "${CMAKE_CURRENT_SOURCE_DIR}/Debug"
    INTERMEDIATE_DIRECTORY_RELEASE "${CMAKE_CURRENT_SOURCE_DIR}/Release"
)

# Add include directories
target_include_directories(LogMsg PRIVATE ${CMAKE_CURRENT_SOURCE_DIR})

# Specify custom build commands
add_custom_command(TARGET LogMsg POST_BUILD
    COMMAND ${CMAKE_COMMAND} -E copy_if_different "${CMAKE_CURRENT_SOURCE_DIR}/LogMsg.rc" "$<TARGET_FILE_DIR:LogMsg>"
    COMMAND ${CMAKE_COMMAND} -E copy_if_different "${CMAKE_CURRENT_SOURCE_DIR}/LogMsg.h" "$<TARGET_FILE_DIR:LogMsg>"
)

如果想简化配置，也可以用生成器表达式统一处理Debug和Release两种配置：

set_target_properties(LogMsg PROPERTIES
    RUNTIME_OUTPUT_DIRECTORY "$<IF:$<CONFIG:Debug>,${CMAKE_CURRENT_SOURCE_DIR}/Debug,${CMAKE_CURRENT_SOURCE_DIR}/Release>"
    INTERMEDIATE_DIRECTORY "$<IF:$<CONFIG:Debug>,${CMAKE_CURRENT_SOURCE_DIR}/Debug,${CMAKE_CURRENT_SOURCE_DIR}/Release>"
)

补充说明 #

• INTERMEDIATE_DIRECTORY_<CONFIG>是Visual Studio生成器特有的属性，专门控制中间编译文件的存放路径。
• 如果Debug/Release目录不存在，CMake会自动创建。
• 若需要同步控制PDB调试文件的输出位置，可额外添加PDB_OUTPUT_DIRECTORY_DEBUG和PDB_OUTPUT_DIRECTORY_RELEASE属性，指向相同的目标目录。
