$(wildcard is a make function, not a binary that you will find on your system.

I don't think that 'which' is a makefile function. To do it that way I think
that the line has to be something like:
ifneq ("$(strip $(shell which genisoimage))", "")
You need to use the $(shell function to call external command. The function
call to strip is to remove any extra spaces that might
have crept in. It probably isn't necessary here, but is safe to have when
comparing to the empty string. I got used to putting
$(strip whenever comparing to the empty string unless I wanted whitespace to
not match.
