系统环境变量读入CMakeSettings.json文件

vcpkgu根

/etc/environment

当我想读入这个变量时 CMakeSettings.json CMake 缓存已挂起。

{
    "environments": [
        {
            "VcpkgRoot": "${env.VCPKG_ROOT}"
        }
    ],
    "configurations": [
        {
            "name": "x64-Debug",
            "generator": "Ninja",
            "configurationType": "Debug",
            "inheritEnvironments": [ "msvc_x64_x64" ],
            "buildRoot": "${projectDir}\\out\\build\\${name}",
            "installRoot": "${projectDir}\\out\\install\\${name}",
            "cmakeCommandArgs": "",
            "buildCommandArgs": "",
            "ctestCommandArgs": "",
            "variables": []
        },
        {
            "name": "WSL-GCC-Debug",
            "generator": "Ninja",
            "configurationType": "Debug",
            "buildRoot": "${projectDir}\\out\\build\\${name}",
            "installRoot": "${projectDir}\\out\\install\\${name}",
            "cmakeExecutable": "cmake",
            "cmakeCommandArgs": "",
            "buildCommandArgs": "",
            "ctestCommandArgs": "",
            "inheritEnvironments": [ "linux_x64" ],
            "wslPath": "${defaultWSLPath}",
            "addressSanitizerRuntimeFlags": "detect_leaks=0",
            "variables": [],
//          "cmakeToolchain": "/scripts/buildsystems/vcpkg.cmake"
            "cmakeToolchain": "${env.VcpkgRoot}"
        }
    ]
}

visualstudio是这样说的

1> CMake generation started for configuration: 'WSL-GCC-Debug'.
1> Found cmake executable at $HOME/.vs/cmake/bin/cmake.
1> $HOME/.vs/cmake/bin/cmake -G "Ninja"  -DCMAKE_BUILD_TYPE:STRING="Debug" -DCMAKE_INSTALL_PREFIX:PATH="/mnt/d/Source/Repos/GoldenWorkshop2020/out/install/WSL-GCC-Debug" -DCMAKE_TOOLCHAIN_FILE:FILEPATH="/mnt//${env.VCPKG_ROOT}"  /mnt/d/Source/Repos/GoldenWorkshop2020/CMakeLists.txt;

我的问题是什么?如何解决?
