@BilalHaider glad to know that you fixed that!
I have a same problem with libGUI, I added the whole libGUI project to my game dependencies (msvs2010), but still get the same linker error 
@iQD @BilalHaider can you please take a look [SOLVED] MSVS 2010 linker error LNK2019 while using ui components (ui::ScrollView)
Regards,
Mike.
