The easiest is probably to build them in-tree by means of
executing ./contrib/download_prerequesites which will download
and unpack them into your source tree.
Other than that you are likely either missing some of the requirements
or lack the appropriate --with-{gmp,mpc,mpfr}[-lib] configury.
What host operating system are you using?
