as I said earlier, I'd probably just use C API calls to libpq, and do my
own C++ wrappings.    C++ libraries pretty much have to be compiled for
the speciifc compiler environment, so I'd have to assume youd load the
libpqxx project source into your IDE, and build it.

with libpq, the OS should already have the .so (or dll if you're on
windows), and .h files, so you'd simply #include <libpq-fe.h>  and call
the various functions using :: in front of the code to indicate they are
not part of a class.  you might have to tell the IDE where the libpq h
and .so files are if they aren't in a standard system library locations
like /usr/include and /usr/lib

I've never used that IDE so I have no idea of the specifics of how you
configure it with new libraries or include files.
