我正在尝试使用 VS2017（和 VS2019RC/preview）构建一个项目/测试 cmake，并将 arm-none-eabi-gcc 作为我的编译器。

我很难告诉 VS2017 在哪里寻找默认的 gcc 标头。

实现这一目标的正确/最简单的方法是什么？

所以我有一个解决方法，很好，工作。但这绝对不是长久之计。

我所做的是直接在CMakeLists.txt'target_include_directories指令中添加了 GCC 包含路径，并且有效。像这样：

target_include_directories(
    ${ELF}
    PRIVATE
        "source"
        "source/target/arm/stm32f1/CMSIS/Device/ST/STM32F1xx/Include"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/include/c++/7.3.1"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/include/c++/7.3.1/arm-none-eabi"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/include/c++/7.3.1/backward"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/include"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/include-fixed"
        "${tools}\\bin\\../lib/gcc/arm-none-eabi/7.3.1/../../../../arm-none-eabi/include"
)

但是，是的，没有人想要这样的解决方案。那么如果有人有更好的主意呢？

我知道我可以像常规包含一样包含它们，但尝试查找配置选项并在下面找到有关如何将其推送到 INCLUDE env 变量的链接。

https://devblogs.microsoft.com/cppblog/arm-gcc-cross-compilation-in-visual-studio/

您可以指定其他包含目录，但请注意，此时还必须显式声明存在的子目录。

[code lang=”js”]
{
// The "environments" property is an array of key value pairs of the form
// { "EnvVar1": "Value1", "EnvVar2": "Value2" }
"environments": [
{
"INCLUDE": "${workspaceRoot}\\src\\includes"
}
],

{
  "configurations": [
    {
      "inheritEnvironments": [
        "gcc-arm"
      ],
      "name": "gccarm",
      "includePath": [
        "${env.INCLUDE}"
      ],
      "defines": [
      ]
    }
  ]
}
