Filtering dependencies

[Maxime Boissonneault]

Hello,
I have a directory structure of this form :
user_exes/
user_exes/exe1/
user_exes/exe1/somefiles.h and .cpp
user_exes/exe2/
user_exes/exe2/somefiles.h and .cpp

I have the following rules :
$(USER_EXES_SUBDIRS_EXES): %$(EXE_EXTENSION) : %.cpp $(filter 
$(@D)%,$(USER_EXES_SUBDIRS_OBJECTS)) $(GSL_OPENMP_OBJECTS)
      $(CPP) $(DIRECTIVES) $(CPPFLAGS) $(INCLUDEDIRS) $(LIBDIRS) $*.cpp 
$(filter $(@D)%,$(USER_EXES_SUBDIRS_OBJECTS)) $(GSL_OPENMP_OBJECTS) 
$(LIBRARIES) -o $*$(EXE_EXTENSION) $(LIBS)

$(USER_EXES_SUBDIRS): $(filter $*%,$(USER_EXES_SUBDIRS_EXES))

$(USER_EXES_SUBDIRS) contains user_exes/exe1/ and user_exes/exe2/
while
$(USER_EXES_SUBDIRS_EXES) contains the name of the executables that are 
to be made.


My problem is that it always builds the 2 executables. How can I make a 
rule such that the dependencies is filtered to contain only those which 
are required, so that only the required stuff is built ?

By the way, I don't want to explicitely list the 
dependencies/directories, since the number of directories will grow.

Thanks
