title: Add additional options in Properties->C/C++->Command Line using Premake
body: <p>I need to add "/FS" to Properties->C/C++->Command Line->Additional Options.</p>
  
  <p>My (shortened) premake.lua:</p>
  
  <pre><code>workspace "test_refactor_edit_control_01"
      platforms { "Win32", "64" }
      configurations { "Debug", "Release" }
  
      filter "platforms:Win32"
          architecture "x86"
  
      filter "platforms:64"
          architecture "x64"
  
  project "test_refactor_edit_control_01"
      location "test_refactor_edit_control_01"
      kind "WindowedApp"
      language "C++"
      staticruntime "Off"
  
      targetdir ("bin/" .. outputdir .. "/%{prj.name}")
      objdir ("bin-int/" .. outputdir .. "/%{prj.name}")
  
  ... (Few more things; nothing special)
  </code></pre>
  
  <p>Using Premake5 and VS2019</p>
