if ANTLR3's header files are not installed into the /usr/include, or
other directories searched by compiler by default. there are chances,
we cannot build the tree. so we have to find it first. as /opt/scylladb
is the directory where `scylla-antlr35-c++-dev` is installed on
debian derivatives, this directory is added so the find package module
can find the header files.
