BES now includes DMR++; hack the configure script WRT libcurl
The DMR++ code is built when --enable-developer is used with configure. When that is the case, require a modern libcurl. Also update the INSTALL and docs.opendap.org notes.
This is an open issue on github: https://github.com/OPENDAP/bes/issues/93
I have started on this using the branch adding-libcurl. I'll work on this when I get a chance. My approach is to use pkg-config and curl-config and still support --with-curl. I have not used AC_CHECK_LIB. Look at the test configure.ac called libcurl_configure.ac and process that using autoconf liburl_configure.ac > libcurl_configure
Lets modify the bes configure.ac so that it tests for different versions of libcurl based on the value set via --enable-developer.
I'll do this...
