c++ - 无法使用 cmake + vcpkg 在 VS Code 中包含 C++ 项目的库

Question

我无法包含通过 vcpkg 安装的第 3 方库。

我正在使用

• Windows 10
• 安装了 C/C++、CMake 和 CMake 工具插件的 Visual Studio Code
• 用于获取 C++ 库的 VCPKG
• Cygwin g++ 编译器
• CMake

C:\Users\Jaiel>g++ --version
g++ (GCC) 10.2.0

C:\Users\Jaiel>vcpkg version
Vcpkg package management program version 2021-05-05-9f849c4c43e50d1b16186ae76681c27b0c1be9d9

C:\Users\Jaiel>cmake --version
cmake version 3.20.3

我试图完成一些测试项目来玩玩。

我尝试过:

• 休息
• wxwidgets
• sqlite3

都失败了。

下面我将概述我对 sqlite3 的尝试:

安装:

The package sqlite3:x86-windows provides CMake targets:

    find_package(unofficial-sqlite3 CONFIG REQUIRED)
    target_link_libraries(main PRIVATE unofficial::sqlite3::sqlite3)


C:\Users\Jaiel>vcpkg integrate install
Applied user-wide integration for this vcpkg root.

All MSBuild C++ projects can now #include any installed libraries.
Linking will be handled automatically.
Installing new libraries will make them instantly available.

CMake projects should use: "-DCMAKE_TOOLCHAIN_FILE=C:/vcpkg/scripts/buildsystems/vcpkg.cmake"

教程.cxx

#include <sqlite3.h>
#include <stdio.h>

int main()
{
    printf("%s\n", sqlite3_libversion());
    return 0;
}

CMakeLists.txt

# CMakeLists.txt
cmake_minimum_required(VERSION 3.0)
project(test)

find_package(unofficial-sqlite3 CONFIG REQUIRED)

add_executable(test tutorial.cxx)

target_link_libraries(test PRIVATE unofficial::sqlite3::sqlite3)

CMake 输出

它根本不适用于上述三个中的任何一个。 wxwidgets 给了我一个不同的错误，即缺少一些 LIBS 和 INCLUDE 路径，但无论我用 google 搜索多少，它都不起作用。

有人可以帮助我吗？

Answer 1

一个技巧是确保在安装 x64 vcpkg 依赖项时使用 x64-windows 调用 cmake。

x86-windows 的想法相同。
