Postgresql 15 client arm64 and Qt 5.15

Hi all,

I should use the client of Postgresql on Arm64, Host where i build is
Ubuntu 20.04 64bit

I have downloaded the library from Ubuntu repository
http://ftp.de.debian.org/debian/pool/main/p/postgresql-15/libpq-dev_15.5-0+deb12u1_arm64.deb

When I am building the library with libpq.a it shows following error,
probably there are missings libraries. Do you know the additional library
that I need to link?
