It can be a little confusing.  --with-odbc-nodm points to the place not
where sql.h is, but where "include/sql.h" is.  That is, it still expects
sql.h (etc.) to be in a directory named "include".  :-/

My setup is like this:

$ cat .build_options
--config-cache
--with-tdsver=7.0 
--with-libiconv-prefix=/usr/pkg 
--enable-threadsafe=no
--disable-libiconv
--with-odbc-nodm=/usr/local

$ ls /usr/local/*/sql.h
/usr/local/include/sql.h

(I have a little script that reads my .build_options file, so I don't have
to remember them or keep them hard-coded in a script.)  

Autoconf is a specialty unto itself, so it's not easy to discern this from
the sources.  For future reference, the answer is to be found in
configure.ac:

$ grep nodm configure.ac
...
if test "$with_odbc_nodm"; then
        if echo "$with_odbc_nodm" | grep -v '^/'; then
                with_odbc_nodm="$PWD/$with_odbc_nodm"
        ODBC_INC="$with_odbc_nodm/include"

and, more clearly, in config.log:

$ grep ODBC_INC build/config.log 
ODBC_INC='-I/usr/local/include'

HTH.
