我想使用这个库见：https ://github.com/jtv/libpqxx

我决定安装这个库管理器 vcpkg 参见：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)

对应的 CMake 代码是这样的：

            set(_VCPKG_TARGET_TRIPLET_ARCH x64)
        elseif(_VCPKG_CL MATCHES "arm/cl.exe$")
            set(_VCPKG_TARGET_TRIPLET_ARCH arm)
        elseif(_VCPKG_CL MATCHES "arm64/cl.exe$")
            set(_VCPKG_TARGET_TRIPLET_ARCH arm64)
        elseif(_VCPKG_CL MATCHES "bin/cl.exe$" OR _VCPKG_CL MATCHES "x86/cl.exe$")
            set(_VCPKG_TARGET_TRIPLET_ARCH x86)
        elseif(CMAKE_HOST_SYSTEM_PROCESSOR STREQUAL "x86_64")
            set(_VCPKG_TARGET_TRIPLET_ARCH x64)
        else()
            if( _CMAKE_IN_TRY_COMPILE )
                message(STATUS "Unable to determine target architecture, continuing without vcpkg.")
            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. 安装的 GIT
  3. 安装的 CMake
  4. 安装的 vcpkg 参见：https ://github.com/microsoft/vcpkg 安装命令：.\bootstrap-vcpkg.bat 5 运行：vcpkg install libpqxx --triplet x64-windows
  5. 运行 : vcpkg list // 查看是否已安装
  6. 运行：vcpkg 集成安装
  7. 在 CLion/CMake 中指定 -DCMAKE-TOOLCHAIN-FILE

我使用 MinGW/GNU 作为编译器

有什么我错过的吗？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：在 Visual Studio 2019 中一切正常

我之前添加-DVCPKG_TARGET_TRIPLET=x64-windows过-DCMAKE_TOOLCHAIN_FILE，它有效。

现在我只需要弄清楚如何链接包含但我想这是另一个问题。

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

使用 CMake，您可以VCPKG_TARGET_TRIPLET在配置行上进行设置：

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 命令行中的不合格三元组，您可以VCPKG_TARGET_TRIPLET在 CMake中默认为

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()
