Mac – Install wget on Mac

I downloaded wget-1.19.tar.gz from this site http://ftp.gnu.org/gnu/wget/ and then i exctract the tar file and run

./configure

The output is that:

checking for ftello... yes
checking for sigblock... yes
checking for sigsetjmp... yes
checking for memrchr... (cached) no

configure: error: Package requirements (gnutls) were not met:

No package 'gnutls' found

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables GNUTLS_CFLAGS
and GNUTLS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.

I found different guides on the web, but none solve my problem. I try to install different package with brew, for example

brew install gnutls

but nothing works. In fact if I do brew install gnutls, seems to be correct, but if i digit

make

the error is that:

    /Library/Developer/CommandLineTools/usr/bin/make  all-recursive

Can anyone help me?

I want to install wget on my Mac because I have to download folders in this page http://www.tlc.dii.univpm.it/fb4fd/ and using curl I can't download them in recursive way.
