find_executable(bin, path = nil)public
Searches for the executable bin on path. The default path is your PATH environment variable. If that isn’t defined, it will resort to searching /usr/local/bin, /usr/ucb, /usr/bin and /bin.
If found, it will return the full path, including the executable name, of where it was found.
Note that this method does not actually affect the generated Makefile.
