If I don't use BUILT_SOURCES, cmapdump binary is not built before
libcmaps, hence cmap_tounicode.c is not created, and compilation of
libcmaps fails.

Is there another solution ?

Yes: just specify cmapdump$(EXEEXT) as prerequisite to cmap_tounicode.c.

isn't what the line:

cmap_tounicode.c: cmapdump $(cmap_tounicode_files)

does ? Note that having that rule is not sufficient on linux (that is, even
if $(EXEEXT) 'should' (but not 'must', as .exe suffix is not necessary) be
added on widnows, it does not work on linux)

In that case you may need to add cmap_tounicode.c to BUILT_SOURCES,
leaving cmapdump out of same.

That shouldn't be necessary; you generally only need to list headers
there for which automake cannot know that they are generated and needed
early.  On GNU/Linux, the example code from the second post from Vincent
should just work.  Vincent, I'm afraid you might just have to debug the
makefile (make -d etc); maybe there is a 'cmapdump' file that make finds
to be matching?

Hmm, i tried with parallal build (make -j 4) and it fails without BUILT_SOURCES.
