Boost 使用 GCC 编译，但不使用 MinGW（使用 CMake）

Question

所以我有一个 C++ 项目，用于从 JSON 文件生成一些批处理文件，我使用 CMake 构建该文件。我使用的是 Windows，但使用 WSL2 可以在 Linux 中完成所有操作。我已经开发了所有内容并使用 GCC 构建了它，但现在我正在测试 MinGW，我在 MinGW 查找 Boost 库时遇到了问题。这是 CMake 配置：

cmake_minimum_required(VERSION 3.10)

# Set some basic project attributes
project (myproject
    VERSION 1.0
    DESCRIPTION "bla bla bla")

# C++ standard
set(CMAKE_CXX_STANDARD 20)

# Add definitions here
# add_definitions(-D....)

# Different versions for Debug and Release
set(CMAKE_CXX_FLAGS_DEBUG_INIT "-Wall -g3 -O0")
set(CMAKE_CXX_FLAGS_RELEASE_INIT "-Wall -O3 -s -pipe")

# Astyle Option in make
add_custom_target (astyle
    COMMAND
    COMMAND astyle -r ${PROJECT_SOURCE_DIR}/*.h ${PROJECT_SOURCE_DIR}/*.cpp --exclude=build
    VERBATIM
)

# Find Doxygen to create documentation
FIND_PACKAGE(Doxygen)

# In case Doxygen is found create a target to create the documentation
if (DOXYGEN_FOUND)
    # Set the input and output file paths
    set(DOXYGEN_IN ${PROJECT_SOURCE_DIR}/Doxyfile)
    set(DOXYGEN_OUT ${PROJECT_SOURCE_DIR}/Doxyfile.doxygen)

    # request to configure the file
    configure_file(${DOXYGEN_IN} ${DOXYGEN_OUT} @ONLY)
    message("Starting doxygen build process")

    # Add a target to create the documentation
    add_custom_target(doc_doxygen # ALL -> In case of automatic build always build all the documentation
        COMMAND ${DOXYGEN_EXECUTABLE} ${DOXYGEN_OUT}
        WORKING_DIRECTORY ${PROJECT_SOURCE_DIR}
        COMMENT "Create doxygen documentation"
        VERBATIM )
else (DOXYGEN_FOUND)
  message("Doxygen not found, not building documentation")
endif (DOXYGEN_FOUND)

# Export file for CMake configuration
configure_file(config.h.in ${PROJECT_SOURCE_DIR}/include/config.h)

# Find Boost
find_package(Boost REQUIRED log_setup log thread system filesystem chrono)

# If installed jsoncpp will be found automatically on UNIX Systems
IF (MINGW)
    # Including JSON-CPP on Windows Systems
    include_directories(${PROJECT_SOURCE_DIR}/jsoncpp/include)
    link_directories(${PROJECT_SOURCE_DIR}/jsoncpp/lib)
ENDIF ()

# Includes
include_directories(${PROJECT_SOURCE_DIR}/include)
include_directories(${PROJECT_SOURCE_DIR}/logging/include)
include_directories(${PROJECT_SOURCE_DIR}/buffer/include)
include_directories(${PROJECT_SOURCE_DIR}/options/include)
include_directories(${PROJECT_SOURCE_DIR}/secFunctions/include)

# Path for final executable (has to be defined before subdirectories)
add_executable(${PROJECT_NAME} main.cpp)

# Subdirectory
add_subdirectory(logging)
add_subdirectory(buffer)
add_subdirectory(options)
add_subdirectory(secFunctions)

# Add libraries
IF (MINGW)
   target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES} jsoncpp wsock32 ws2_32)
ELSE (MINGW)
   target_link_libraries(${PROJECT_NAME} ${Boost_LIBRARIES} jsoncpp)
ENDIF ()

使用 GCC 11.4 构建时一切正常，但是当我使用 MinGW（GCC 10）时，一切都崩溃了。我收到以下错误消息：

CMake Error at /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
[cmake]   Could NOT find Boost (missing: log_setup log thread system filesystem
[cmake]   chrono) (found version "1.74.0")
[cmake] Call Stack (most recent call first):
[cmake]   /usr/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:594 (_FPHSA_FAILURE_MESSAGE)
[cmake]   /usr/share/cmake-3.22/Modules/FindBoost.cmake:2360 (find_package_handle_standard_args)
[cmake]   CMakeLists.txt:54 (find_package)

我尝试重写 MinGW 的 CMake 配置，然后在编译时“工作”，但在构建项目时，它根本无法识别 Boost。我做错了什么？

Answer 1

一个脏的解决方案是将 Boost Libraries 的根文件夹设置为包含它们的 GCC 文件夹。对我来说这是：

set(Boost_ROOT "usr/lib/x86_64-linux-gnu/cmake/")

一个更清洁的解决方案是执行以下命令：

(sudo) cp -r path_to_gcc/lib/cmake/ path_to_mingw/lib/

并删除上面的代码。
我不确定这是否是一个好的解决方案，因为我不知道 MinGW 是否需要不同的库才能与 CMake 和 Boost 真正兼容，但这应该有效。
