How to get meson to use a library in a different lib directory?

I have two versions of a library, zita-convolver3 and zita-convolver4. The system library is zita-convolver3, but i want to link against zita-convolver4, which is stored in a local user directory. How do i get meson to compiler.find_library zita-convolver4 instead of prioritising the system version zita-convolver3? I can work around this by using a pkg-config file and setting the pkgconfig_path to explicitly set this. But is there a way of doing it using only meson?
