This won't work because the expansion order is wrong: all variables and
functions are expanded FIRST, before the static patterns are handled.

So, $(wildcard %*) is expanded literally and, unless you have some files
that begin with "%" in your directory, it expands to the empty string.

The only way you can do something like this without writing a separate
line for every target is to use the eval function (first available in
GNU make 3.80), or to use the "auto-re-exec" trick.
