' Open the Macro Explorer (Tools/Macros/Macro Explorer), create a new Module, and add the following subroutine:
    Sub RunPremake()
        If Not DTE.Solution Is Nothing And Not String.IsNullOrEmpty(DTE.Solution.FullName) Then
            Dim solutionPath, solutionDir, premakeTarget, premakeFlags, premakeExePath, premakeScriptDir As String
            solutionPath = DTE.Solution.FullName
            solutionDir = solutionPath.Substring(0, solutionPath.LastIndexOf("\"))
            premakeTarget = solutionDir.Substring(solutionDir.LastIndexOf("\") + 1)

            ' You might need to adjust these
            premakeFlags = ""
            premakeExePath = "C:\premake\premake4.exe"   ' need to be changed
            premakeScriptDir = solutionDir + "\..\.."    ' need to be changed

            DTE.ExecuteCommand("File.CloseSolution")
