Set PKG_CONFIG_PATH to the location of your pkgconfig files. Autotools
will use the correct flags for the library.

Based on your LDFLAGS, I can't really tell what is should be. I'm not
clear on the directory structure in $HOME. If things were installed in
/usr/local, then the following would do it:

    # Everything goes into /usr/local
    export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
    ./configure --prefix=/usr/local ...
