checking PostgreSQL failed

[AlessandroBalestrucci]

I am trying to execute the following command:
./configure --prefix=/opt/pgadmin3bigsql --with-libgcrypt --with-wx-version=3.0 CFLAGS=-fPIC CXXFLAGS=-fPIC --with-pgsql=/usr/lib/postgresql/12

then I got these last lines:
...
checking PostgreSQL in /usr/lib/postgresql/12... failed
configure: error: you must specify a valid PostgreSQL 8.4+ installation with --with-pgsql=DIR

the command: locate bin/postgres -> /usr/lib/postgresql/12/bin/postgres
Can someone help me to solve this issue?

@AlessandroBalestrucci You did not have required PostgreSQL at /usr/lib/postgresql/12 . You can try omit --with-pgsql option or try to use different version, e.g. 13.

Did you install development packages?
