To build from the command line, specify the path to a compiled Kakadu directory, e.g.

cmake . -DKakadu_Dir=../kakadu-7.A.5

To build in MSVC, specify the same variable in CMakeSettings.json, e.g.

{
  "configurations": [
    {
	  // ...
      "variables": [
        {
          "name": "Kakadu_Dir",
          "value": "${env.USERPROFILE}\\kakadu\\kakadu-7.A.7\\v7_A_7-00307L"
        }
      ]
    }
  ]
}
