Get the 4 header files from the page below and put in one directory.
https://github.com/troydhanson/uthash/tree/master/src
Specify the directory path when running configure with "--with-uthash". Here is as an example of what I ran., and the uthash header files were under /root/dhcp/dhcpd-pools-2.26/contrib/uthash/src/
./configure --with-uthash=/root/dhcp/dhcpd-pools-2.26/contrib/uthash/src/ --with-dhcpd-conf=/etc/dhcpd.conf --with-dhcpd-leases=/var/lib/dhcpd/dhcpd.leases
