19 dnl Generally, it is a bad idea to put specialized header files for a library
20 dnl into a generic directory like /usr/local/include/. Instead, one should put
21 dnl them into a subdirectory. GiNaC does it, NTL does it. Unfortunately, CLN
22 dnl doesn't do so but some people choose to do it by hand. In these cases we
23 dnl need to #include <CLN/cln.h>, otherwise #include <cln.h>. This macro
24 dnl tries to be clever and find out the correct way by defining the variable
25 dnl HAVE_CLN_CLN_H in config.h:

35 dnl This macro is needed because the generic AC_CHECK_LIB doesn't work because
36 dnl C++ is more strongly typed than C. Therefore we need to work with the
37 dnl more fundamental AC_TRY_LINK instead.
