[Interest] Building Qt from source ('libpq-fe.h' file not found)

[Nuno Santos]

I have just called ./configure —prefix=/path/to/build

Curiously, this is what configure says about sql drivers:

    -no-sql-<driver> ... Disable SQL <driver> entirely.
    -qt-sql-<driver> ... Enable a SQL <driver> in the Qt SQL module, by default
                         none are turned on.
    -plugin-sql-<driver> Enable SQL <driver> as a plugin to be linked to
                         at run time.

                         Possible values for <driver>:
                         [ db2 ibase mysql oci odbc psql sqlite sqlite2 tds ]

I have tried to make ./configure -no-sql-psql and that didn’t made any difference.
