How to assign a custom icon to an application that is compiled from the source file?

In my program, I use CSharpCodeProvider in order to compile another application from the source file, I use the code below:

public static bool CompileExecutable(String sourceName)
{
    FileInfo sourceFile = new FileInfo(sourceName);
    CodeDomProvider provider = null;
    bool compileOk = false;

    // Select the code provider based on the input file extension.
    if (sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) == ".CS")
        provider = CodeDomProvider.CreateProvider("CSharp");
    else if (sourceFile.Extension.ToUpper(CultureInfo.InvariantCulture) == ".VB")
        provider = CodeDomProvider.CreateProvider("VisualBasic");
    else
    {
        Console.WriteLine("Source file must have a .cs or .vb extension");
    }
    if (provider != null)
    {
        // Format the executable file name.
        // Build the output assembly path using the current directory
        // and <source>_cs.exe or <source>_vb.exe.

        String exeName = String.Format(@"{0}\{1}.exe",
            System.Environment.CurrentDirectory,
            sourceFile.Name.Replace(".", "_"));

        CompilerParameters cp = new CompilerParameters();

        // Generate an executable instead of  a class library.
        cp.GenerateExecutable = true;

        // Specify the assembly file name to generate.
        cp.OutputAssembly = exeName;

        // Save the assembly as a physical file.
        cp.GenerateInMemory = false;

        // Set whether to treat all warnings as errors.
        cp.TreatWarningsAsErrors = false;

        cp.ReferencedAssemblies.Add("System.dll");
        cp.ReferencedAssemblies.Add("System.Windows.Forms.dll");
        cp.ReferencedAssemblies.Add("mscorlib.dll");
        cp.ReferencedAssemblies.Add("Microsoft.VisualBasic.dll");

        // Invoke compilation of the source file.
        CompilerResults cr = provider.CompileAssemblyFromFile(cp,
            sourceName);

        if (cr.Errors.Count > 0)
        {
            // Display compilation errors.
            Console.WriteLine("Errors building {0} into {1}",
                sourceName, cr.PathToAssembly);
            foreach (CompilerError ce in cr.Errors)
            {
                Console.WriteLine("  {0}", ce.ToString());
                Console.WriteLine();
            }
        }
        else
        {
            // Display a successful compilation message.
            Console.WriteLine("Source {0} built into {1} successfully.", sourceName, cr.PathToAssembly);
        }

        // Return the results of the compilation.
        if (cr.Errors.Count > 0)
            compileOk = false;
        else
            compileOk = true;
    }
    return compileOk;
}

I put a file with the name (source.cs) that contains the source code of the program I want to compile, I put it in the same directory as my application, and call the function from my application

CompileExecutable("source.cs");

Then the source code is compiled and saved in the same directory as my application.

What I'm trying to do now is add a parameter that allows me to select a custom icon for the compiled source code, so the icon will be selected for the executable output file, but I don’t know how I can assign an executable output icon before compiling it.
