Hitting issues with deploying govips image compression with DO Functions

# pkg-config --cflags  -- vips
Package vips was not found in the pkg-config search path.
Perhaps you should add the directory containing `vips.pc'
to the PKG_CONFIG_PATH environment variable
No package 'vips' found
pkg-config: exit status 1

with the following code

package main

import (
  "fmt"
  "io"
  "net/http"
  "os"

  "github.com/davidbyttow/govips/v2/vips"
)

func checkError(err error) {
  if err != nil {
    fmt.Println("error:", err)
    os.Exit(1)
  }
}

func Main() {
  vips.Startup(nil)

  _// fetch image_
  url := "https://images.pexels.com/photos/45201/kitty-cat-kitten-pet-45201.jpeg"
  response, _ := http.Get(url)

  image1bytes, err := io.ReadAll(response.Body)
  checkError(err)
  image1, err := vips.NewThumbnailFromBuffer(image1bytes, 200, 200, vips.InterestingCentre)

  checkError(err)

  _// Rotate the picture upright and reset EXIF orientation tag_
  err = image1.AutoRotate()
  checkError(err)

  ep := vips.NewDefaultJPEGExportParams()
  image1bytes, _, err = image1.Export(ep)
  checkError(err)
  err = os.WriteFile("output.jpg", image1bytes, 0644)
  checkError(err)
  vips.Shutdown()
}

would love some insight on what to do. I tried finding this in the docs somewhere but I had no luck.

Thanks!
