ading a make rule to a .la (or another) file

Hello

Here is a description of my problem:

I have the following files :

etui/
  Makefile.am (which includes src/modules/pdf/Makefile.mk)
  src/
    modules/
      pdf/
        Makefile.mk
        etui_module_pdf.c
        mupdf-1.10a/
          Makefile
          other mupdf files

I my Makefile.mk, I already have :

------------------

etui_modules_pdf_LTLIBRARIES = src/modules/pdf/module.la

src_modules_pdf_module_la_SOURCES = \
src/modules/pdf/etui_module_pdf.c \
src/modules/pdf/etui_module_pdf.h

src_modules_pdf_module_la_LIBADD = \
src/lib/libetui.la \
-L$(abs_srcdir)/src/modules/pdf/mupdf-1.10a/build/release -lmupdf \
-L$(abs_srcdir)/src/modules/pdf/mupdf-1.10a/build/release -lmupdfthird \
@ETUI_LIBS@

------------------

But etui_module_pdf.c needs to build mupdf shared library and link
against it, that is, just run 'make' in mupdf-1.10a/

So, in my Makefile.mk, I  would like to do something like:

src/modules/pdf/src_modules_pdf_module_la-etui_module_pdf.lo: buildmupdf

buildmupdf:
    cd src/modules/pdf/mupdf-1.10a && make

but 'make' is never called before the link (or compilation) of my
module. I have tried to use .la, or .o for the file, without any luck

Does someone know what I should add to build mupdf *before* the link
of my module ?

thank you

Vincent Torri
