Load pre-compiled library in root interpreter

TString libFilename = "libMyLibName";
    
TString DirName = TString(gSystem->GetWorkingDirectory());
if( !(DirName.EndsWith("/build") || DirName.EndsWith("/build/")) ){
    DirName = DirName + TString("/build/");
}
if( !(DirName.EndsWith("/")) ){
    DirName = DirName + TString("/");
}
  
TString libIncludePath = TString::Format("%sinclude", DirName.Data());
TString libLoadPath = TString::Format("%s%s", DirName.Data(), libFilename.Data());

gInterpreter->AddIncludePath(libIncludePath);
gInterpreter->Load(libLoadPath, true);
gSystem->Load(libLoadPath);
