I wonder to know if there is a tar.gz of that branch, i did try using from
this page: https://code.launchpad.net/~rousskov/squid/DynamicSslCert
by doing a

bzr branch http://bazaar.launchpad.net/~rousskov/squid/DynamicSslCert

then I run bootstrap.sh and configure script was created,
but if a di a grep -r enable-ssl-crtd * to search about that option but I
couldnt find anything,

is there something i was missing or I have just tu compile to have
generate-host-certificates=on dynamic_cert_mem_cache_size=4MB available

TIA
