Advanced expansion of prereg pattern?

[Lars Noschinski]

Hello!

I have the following directory structure:

exercise01.tex
exercise01/a-drawing.fig
exercise01/another-figure.fig
exercise02.tex
exercise02/...

So I want to compile the .tex files, which depend on the .fig files
converted to .eps before.

My first try was a rule like the first one below (I know it is not
correct, but I think it is clear what I try to achieve):

%.pdf: %.tex %/*.eps
    .....

%.eps: %.fig
    .....

This will obviously not work, and it seems also impossible to replace
"%/*.eps" like
    
    $(wildcard $@/*.eps)
    
or
    $(filter $@/%,$drawings)

where $drawings is a list of all fig files in all subdirectories.

So it looks to me like I would need to generate dependencies by using an
little shell script, but before I do this, I want to be sure that make
cannot do this for itself ;)
