so, it detected header but cppflags/cflags still not updated.
I found gl_ABSOLUTE_HEADER macro from gnulib/m4 but it only adds '-D PATH_TO_HEADER=///path_to_header' gcc flags and PATH_TO_HEADER define to config.h
I thought confuge not just find libs but alters cflags/cppflags/ldflags - but apparently our does not quite work this way..
theres was AC_LIB_LINKFLAGS https://www.gnu.org/software/gnulib/manual/html_node/ Searching-for-Libraries.html
but it also assumes " These macros assume that when a library is installed in some_directory/lib, its include files are installed in some_directory/include."
in our case this is wrong..
so I am stuck at adding one more " -I" directive to configure.ac...

can you send me config.log too? (to see if configure picked up liba52/a52.h header)
