Pws mborw mesa apo to makefile na kalesw ena bash script?

Exw ena script pou rithmizei diafora path klp, arketa megalo, to
usr/local/lala.sh.
Thelw na mborw na to kalw mesa apo to makefile, *prin* apo ta targets.

To  makefile einai kapws etsi:

<MakefileSnippet>

include Makefile.arch
FOO := foo
BAR = bar

PLATFORM=$(shell uname)
SRCS    = $(wildcard *.cpp)

# !!!!!!!!!!!!!!!!!
[megalo  snip]

$(BLAHINSTALL)/config/binmake.gmk
name := MyDetSim
BLAHTARGET := $(name)

[ki allo megalo snip]

%:%.o
    $(LD) $(LDFLAGS) $(GLIBS) $(CXX) $(FLAGS) $^ -o $@

$(OBJS): %.o: %.cpp $(HDRS)
    @echo "Compiling $< with $(CXX) ..."
    $(CXX)  $(CXXFLAGS)  $(CPPFLAGS)  $(FLAGS) -c $< -o $@

targ:     targ.o classaaa.o classbbb.o classccc.o
    @echo "Building $@ ..."
    $(LD) $(LDFLAGS) $(GLIBS) $(OutPutOpt) $(CXX) $(FLAGS) \
    targ.o classaaa.o classbbb.o classccc.o -o $@

</MakefileSnippet>

Twra, thelw na valw kapou  *prin to $(BLAHINSTALL)/config/binmake.gmk*
kati san

ifndef BLAHINSTALL
bash -c "source /usr/local/lala.sh"
endif
(nai, fysika afto den doulevei...)

opou to lala.sh periexei kai ton orismo otu BLAHINSTALL, diafora
INCLUDES  (kai ektelei kai diafora alla).

Ti kserw:
1. Tha mborousa na to kanw ftiaxnontas ena target, eg:

testblah:
    ifndef BLAHINSTALL
    bash -c "source /usr/local/lala.sh"
    endif
targ:     testblah targ.o classaaa.o classbbb.o classccc.o
    @echo "Building $@ ..."
    $(LD) $(LDFLAGS) $(GLIBS) $(OutPutOpt) $(CXX) $(FLAGS) \
    targ.o classaaa.o classbbb.o classccc.o -o $@

alla to BLAHINSTALL xreiazetai na einai orismeno hdh prin apo ta
targets (amesws meta th grammh sxolio me ta  "!!!" ).
Epomevw to make den ftanei pote sto testblah, crasharei me minima
"den vriskw to /config/binmake.gmk".

2. Mborw na orisw to $(BLAHINSTALL) sthn defteri grammi tou makefile,
alla oute afto mou kanei (yparxoun kammia eksintaria grammes sto makefile
pou den tis deixnw edw, alla pou preepi kai aftes na allaksoun me ton idio
tropo)

3. Mporw na ftiaksw ena allo script pou, afou kalesei to lala.sh
meta tha kalei to make (afti einai i moni lisi pou kserw na doulevei)
