Shouldn't your compiler check this directory anyways?  Strange it doesn't.
BTW, this *is* documented in the tutorial's section about configuration
with the only difference in path: CPPFLAGS="${CPPFLAGS} -I${HOME}/include"

Exactly as I did, except that we use includedir=/usr/local/include/CLN
here.  I guess the uppercase spelling is depricated by some people out
there.  In acinclude.m4 the Macro GINAC_CHECK_CLN_H does attempt to do
exactly this but the macro AC_CHECK_HEADERS puts it result in uppercase
always so there is no nice Autoconf-way to distinguish between cln/cln.h 
and CLN/cln.h.  Hope you can live with that.  Maybe a future version of
CLN does this.
