Meson - How to specify which wxgtk version to use?

I'm using Arch Linux and working on a project using wxgtk3 which I installed from pacman, I also installed wxformbuilder from the AUR which pulls in wxgtk2 as a dependency. When I try to build my program, it builds fine, but when I try to run it, it throws a huge error message,
Code:.
.
./src/common/object.cpp(245): assert "classTable->Get(m_className) == NULL" failed in Register(): Class "wxTreebook" already in RTTI table - have you used IMPLEMENT_DYNAMIC_CLASS() multiple times or linked some object file twice)?

(SampleHive:26191): Gtk-ERROR **: 05:45:13.924: GTK+ 2.x symbols detected. Using GTK+ 2.x and GTK+ 3 in the same process is not supported
zsh: trace trap ./SampleHivethis is only a small section of the error..

But if I uninstall wxgtk2 and try to run my program again, it runs fine. Is there a way to specify in meson to always use wxgtk3, so I don't have to uninstall wxgtk2 again and again, as I need wxformbuilder installed on my system, both wxgtk3 and wxgtk2 are same versions, i.e 3.0.5, I want to specify if it should use wx-config-gtk3 which is wxgtk3 or wx-config which is wxgtk2.
