Both Greg and Brian suggest modifying the build rule to specify the PATH.
Which is fine as far as it goes, but doesn't necessarily help ElenaR if
she's relying on the implicit built-in rules.
If you want to change the $PATH setting used by implicit rules, it might
work to add a pattern-specific definition. For instance, to add /some/path to
$PATH whenever a C file is being compiled to an object file by an implicit
rule, you could try
%.o : PATH=/some/path:$(PATH)
Alternatively, since the implicit rules always use a variable to specify the
compiler invoked, you can try redefining those to have a full path instead,
i.e.
CC:=/some/path/gcc
CXX:=/some/path/g++
etc.
