How can I get VSCode's LaTeX Workshop to find the right installation of TeX?

Question

I've installed TeX Live and Visual Studio Code with the LaTeX Workshop extension. Previously, I'd installed LyX. VSCode is looking at the LyX installation. I know this because I had an error complaining it couldn't find a library and it listed the LyX install directory. When I copied the folder from TeX Live to LyX's directory, that error went away. The problem is, I would prefer to use TeX Live. It already has packages I need installed. How can I get VSCode and the LaTeX extension to look at the TeX Live directory? I've looked at the settings and don't see anything that sets that path.

EDIT: I've tried following the information on James Wu's page but I am new to LaTeX and not succeeding. Note that I'm trying to follow instructions given here to format a poem. I am using the example from that article for my test.

My recipe is:

[  {
"name": "latexmk 🔃",
"tools": [
  "latexmk"
]   },  {     "name": "latexmk",
"command": "latexmk",
"args": [
  "-synctex=1",
  "-interaction=nonstopmode",
  "-file-line-error",
  "-pdf",
  "-outdir=%OUTDIR%",
  "%DOC%"
],
"env": {"TEXMFHOME": "c:/texlive/2019"}   } ]  

The errors I am getting are:

Answer 1

I figured out how to change the path. In VSCode, click on Extensions (the icon with the 4 boxes). Then select LaTeX Workshop and click on Settings. Scroll down to Latex Workshop -> Latex: Tools. Click on "Edit Settings in Json" and type in the following:

[
  {
    "name": "latexmk",
    "tools": [
      "latexmk"
    ]
  },
  {
    "name": "latexmk",
    "command": "latexmk",
    "args": [
      "-synctex=1",
      "-interaction=nonstopmode",
      "-file-line-error",
      "-pdf",
      "-outdir=%OUTDIR%",
      "%DOC%"
    ],
    "env": {"TEXMFHOME": "c:/texlive/2019"}
  }
] 

Set your TEXFMHOME path as needed. Save. This should get you the installation you want.
