[CMake] Problem with Static Pattern Rules

[Carminati Federico]

Hello,
   it is possible to add a custom command to cmake with a static  
pattern rule? My problem is the following, I have a coding convention  
checker that for each c++ source file creates a "violation" file. The  
rule I had in my makefile was

$(SRCS:.cxx=.viol) : %.viol : %.cxx
      bla bla

How can I do this in cmake? The only way that seems to work is to  
create a single rule for each file with foreach. Is there a better  
way? best,
