My solution was to create a c# class to read ini files, get the project dir + “/config/defaultengine.ini” file and grab the values:
/// <summary>
/// A class for reading values by section and key from a standard ".ini" initialization file.
/// </summary>
/// <remarks>
/// Section and key names are not case-sensitive. Values are loaded into a hash table for fast access.
/// Use <see cref="GetAllValues"/> to read multiple values that share the same section and key.
/// Sections in the initialization file must have the following form:
/// <code>
/// ; comment line
/// [section]
/// key=value
/// </code>
/// </remarks>
public class IniFile
{
/// <summary>
/// Initializes a new instance of the <see cref="IniFile"/> class.
/// </summary>
/// <param name="file">The initialization file path.</param>
/// <param name="commentDelimiter">The comment delimiter string (default value is ";").
/// </param>
public IniFile(string file, string commentDelimiter = ";")
{
CommentDelimiter = commentDelimiter;
TheFile = file;
}
/// <summary>
/// Initializes a new instance of the <see cref="IniFile"/> class.
/// </summary>
public IniFile()
{
CommentDelimiter = ";";
}
/// <summary>
/// The comment delimiter string (default value is ";").
/// </summary>
public string CommentDelimiter { get; set; }
private string theFile;
/// <summary>
/// The initialization file path.
/// </summary>
public string TheFile
{
get
{
return theFile;
}
set
{

dictionary.Clear();

{
theFile = value;
using (StreamReader sr = new StreamReader(theFile))
{

example of use:
var defaultEngineIniFile = new IniFile(target.ProjectFile.Directory.FullName + "/Config/DefaultEngine.ini");
bool bBuildForArmV7 = defaultEngineIniFile.GetBoolean("/Script/AndroidRuntimeSettings.AndroidRuntimeSettings",
"bBuildForArmV7", true);
