+Use a cmd prompt with admin privilege:
+```
+cd base-directory-of-wireshark-smf-plugin

+mklink CMakeListsCustom.txt ..\src\CMakeListsCustom.txt 
+cd plugins\epan
+mklink /D smf ..\..\..\src\smf
+```
+In vscode, my task.json looks like this:

+Note 1: To start VSCode, start from the "X64 Native Tools Command Prompt" (search for this in Windows search box), then type "code" to start VSCode.
+
+Note 2: The VCSVERSION_OVERRIDE is needed because the compile failed to find the approparite git repository.
