Definitely. And why should it?
The wildcard function is a builtin function in GNU make (using the GNU C
runtime globbing functions directly). Make does not invoke a shell or
anything to handle wildcarding.
So, the shell does not expand your environment variables; instead if you
had a filename like $ROOT/foodir make looks for path with the literal
string '$ROOT/foodir', not whatever $ROOT expands to.
