You mean,
sourcefile_c_CPPFLAGS
and
target_CPPFLAGS
are contradictory? I can live very well with one of them being incremental:
sourcefile_c_ADDED_CPPFLAGS = -DLIBDIR=\"$(libdir)\"
so that the entire CPPFLAGS will be the combination:
$(target_CPPFLAGS) $(sourcefile_c_ADDED_CPPFLAGS)
Or you mean, if someone uses the same source file with different targets
_and_ wants to specify different CPPFLAGS for both compilations:
target1_SOURCES = ... sourcefile.c ...
target2_SOURCES = ... sourcefile.c ...
This is a rare case; I think in this case the workaround of
target1_SOURCES = ... sourcefile1.c ...
target2_SOURCES = ... sourcefile2.c ...
EXTRA_DIST = sourcefile.c
sourcefile1.c ::= #include "sourcefile.c"
sourcefile2.c ::= #include "sourcefile.c"
is acceptable.
