c++ - 如何修复 'Vcpkg/CMake Is Unable to determine target architecture'(Windows10、vcpkg、clion、cmake)

Question

我想使用这个库，请参阅:https://github.com/jtv/libpqxx

我决定安装这个库管理器vcpkg，请参阅:https://github.com/microsoft/vcpkg

我将 CMake 选项设置为“CMake 项目应使用:”-DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake”

这是错误:

"C:\Program Files\JetBrains\CLion 2019.1.4\bin\cmake\win\bin\cmake.exe"     -DCMAKE_BUILD_TYPE=Debug -DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/vcpkg/scripts   /buildsystems/vcpkg.cmake -G "CodeBlocks - MinGW Makefiles" C:\Users  \Vaio\CLionProjects\untitled
CMake Warning at C:/vcpkg/vcpkg/scripts/buildsystems/vcpkg.cmake:68   (message):
Unable to determine target architecture, continuing without vcpkg.
Call Stack (most recent call first):
cmake-build-debug-mingw/CMakeFiles/3.14.3/CMakeSystem.cmake:6 (include)
CMakeLists.txt:2 (project)

对应的CMake代码是这样的:

            else()
                message(WARNING "Unable to determine target architecture, continuing without vcpkg.")
            endif()
            set(VCPKG_TOOLCHAIN ON)
            return()
        endif()
    endif()
endif()

这是我所做的一步一步。

1. 已安装 Visual Studio 2019
2. 已安装 GIT
3. 已安装 CMake
4. 已安装 vcpkg，请参阅:https://github.com/microsoft/vcpkg安装命令:.\bootstrap-vcpkg.bat5 运行:vcpkg install libpqxx --triplet x64-windows
5. 运行 : vcpkg list//查看它是否已安装
6. 运行:vcpkg集成安装
7. 在 CLion/CMake 内指定 -DCMAKE-TOOLCHAIN-FILE

我使用 MinGW/GNU 作为编译器

是不是我漏掉了什么？或者为什么它找不到我的目标架构？这是我的环境变量。

注意:Visual Studio 2019 中一切正常

我在 -DCMAKE_TOOLCHAIN_FILE 之前添加了 -DVCPKG_TARGET_TRIPLET=x64-windows 并且它起作用了。

解决方案链接: https://vcpkg.readthedocs.io/en/latest/users/integration/

使用 CMake，您可以在配置行上设置 VCPKG_TARGET_TRIPLET:

cmake ../my/project -DVCPKG_TARGET_TRIPLET=x64-windows-static -DCMAKE_TOOLCHAIN_FILE=...

如果您使用VCPKG_DEFAULT_TRIPLET环境变量来控制vcpkg命令行中的非限定三元组，您可以在CMake中默认VCPKG_TARGET_TRIPLET，例如

使用环境变量而不是命令行选项:

if(DEFINED ENV{VCPKG_DEFAULT_TRIPLET} AND NOT DEFINED VCPKG_TARGET_TRIPLET)
  set(VCPKG_TARGET_TRIPLET "$ENV{VCPKG_DEFAULT_TRIPLET}" CACHE STRING "")
endif()
