Using eval with wildcard function

[hans . peter . van . lohuizen]

Hi 
I use gmake 3.80.

I have the following lines to generate a wildcard in a set of rules preceeded by a path added via %:

 tmp = $(wildcard cmd/*.tcl)

 DEP_CMD=$(foreach OBJ, % ,$(addprefix %, $(tmp)))

The wildcard failes because it is only filled in once for the first % only.
So I tried to use the eval function to re-evaluate the wildcard for all separate %:

 DEP_CMD=$(foreach OBJ, % ,$(addprefix %, $(eval $$(tmp)) ))

But now I get the message: "missing separator" 

I also tried the value function:
 
DEP_CMD=$(foreach OBJ, % ,$(addprefix %, $(eval $(value tmp) ) ))

But still get the missing separator message.
Can somebody tell me what is wrong?

Thanks a lot!

Hans Peter.
