        This macro provides a compile-time ability to inject Microsoft Installer Database file properties at compile time.
 
    Example:
        ${!MSIPropertyGet} "SomePackage.ProductName"    "SomePackage.msi" "ProductName"
        ${!MSIPropertyGet} "SomePackage.ProductVersion" "SomePackage.msi" "ProductVersion"
 
        !define DisplayName `${SomePackage.ProductName} v${SomePackage.ProductVersion}`
        OutFile Test.exe
        Name `${DisplayName} Special Build`
