Searching for an error string is always a bad idea.  What if the user
has their locale set to display errors in German?  You'd go crazy trying
to search for all the different ways of saying "command not found" in
every shell and every language.

It's not necessary either as the shell gives you a status value when a
command fails to execute a command, which you can test e.g.

foo := $(shell doxygen --version >/dev/null 2>&1 && echo "yes")

...will result in foo being "yes" if the command was successful
otherwise blank.  If you want yes/no then you can do something like:

foo := $(shell if cmd; then echo yes; else echo no; fi)
