Described here: https://www.gnu.org/software/automake/manual/html_node/Flag-Variables-Ordering.html Basically, if you explicitly define CFLAGS,CPPFLAGS,LDFLAGS,etc for a target like inst_LTLIBRARIES = /path/to/libtarget.la path_to_libtarget_CPPFLAGS = -ABC then this gets build with $(path_to_libtarget_CPPFLAGS) $(CPPFLAGS). Otherwise, it gets $(AM_CPPFLAGS) $(CPPFLAGS) Thomas
