如何使 FindBoost.cmake 静态库搜索适应 x32 增强库？

Question

问题：

我正在尝试在我的项目中包含一个自建的 boost 库。我正在使用 cmake 构建文件，并且遇到 Findboost.cmake 找不到已编译库的问题。如果您查看 cmake 调试信息，它似乎在搜索错误的库名称。

这里是一个错误库名的例子：

目前：

• libboost_regex-mgw82-mt-d-1_71

想要的：

• libboost_regex-mgw82-mt-d-x32-1_71

我的意思是我可以手动重命名文件，但我认为这不是唯一的解决方案。有什么办法可以告诉 cmake 添加“x32”部分吗？或者也许我必须给 boost 一个特殊的编译输入？

Cmake 文件和命令：

cmake_minimum_required(VERSION 3.14)
project(clion)

set(CMAKE_CXX_STANDARD 14)
set(Boost_USE_STATIC_LIBS ON)
set(Boost_USE_MULTITHREADED ON)
find_package(Boost 1.71.0 COMPONENTS regex REQUIRED)

if (Boost_FOUND)

    include_directories(${Boost_INCLUDE_DIRS})
    add_executable(clion main.cpp)
    target_link_libraries(clion ${Boost_LIBRARIES})

endif ()

cmake -G "MinGW Makefiles" -DBoost_DEBUG=TRUE .

调试输出：

这是完整的输出：

    cmake -G "MinGW Makefiles" -DBoost_DEBUG=TRUE .

Answer 1

试试：

set(Boost_COMPILER "-x32")

根据FindBoost reference：

Boost_COMPILER           - Set to the compiler-specific library suffix
                           (e.g. "-gcc43").  Default is auto-computed
                           for the C++ compiler in use.

正如@kenba 所建议的，Boost_ARCHITECTURE 也可以工作并且在技术上更正确。

Answer 2

我认为您的问题是由FindBoost.cmake 未在boost 1.66.0 及以上版本中正确处理MinGw 库名称引起的，如答案here 中所述。

将set(Boost_ARCHITECTURE "-x32") 添加到您的CMakeLists.txt 文件或将-DBoost_ARCHITECTURE="-x32" 添加到您的cmake 命令应该可以修复它。
