Building CUDA in platformio-ide-terminal

I would like to be able to compile and build CUDA C source code provided here using Windows 10 Powershell. I have no issue doing this using x64 Native Tools Command Prompt for VS 2017.

However, I have tried several ways suggested online to get Powershell to work, but no success. The reason is I want to be able to build my cuda codes in Atom, the editor, using its package platformio-ide-terminal that loads a Powershell inside Atom. So, if I figure out how to setup Visual Studio 2017 Community in a Powershell, I edit my code in Atom and conveniently build them using its Powershell integration.

I tried to set the environment as follows but still nvcc cannot find the path to cl.exe.

Could someone kindly help me?

    Automation

    To automate this, create a file named nvcc_setup_for_powershell.ps1 and place the following two commands in it.

    & 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Auxiliary\Build\vcvarsall.bat' amd64
$ENV:PATH="$ENV:PATH;C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\VC\Tools\MSVC\14.14.26428\bin\Hostx64\x64"
Write-Output "Configured PowerShell for NVCC Using Visual Studio 2019 Community x64"
$myshell = New-Object -com "Wscript.Shell"
$myshell.sendkeys("{ENTER}")

    the last two commands is to simulate hitting enter button, adopted from here.

    Open settings for platformio-ide-terminal under Core > Run Command place the path to the PowerShell script: & "C:\Path\To\Script\nvcc_setup_for_powershell.ps1".

    enter image description here You may need to open a PowerShell as administrator and run the following command

    Set-ExecutionPolicy RemoteSigned

    to allow you to execute nvcc_setup_for_powershell.ps1.
