parameters: (cmd)
return_statement: return path
docstring: Find absolute path to executable cmd in a cross platform manner.
  
      This function tries to determine the full path to a command line program
      using `which` on Unix/Linux/OS X and `win32api` on Windows.  Most of the
      time it will use the version that is first on the users `PATH`.
  
      Warning, don't use this to find IPython command line programs as there
      is a risk you will find the wrong one.  Instead find those using the
      following code and looking for the application itself::
  
          from IPython.utils.path import get_ipython_module_path
          from IPython.utils.process import pycmd2argv
          argv = pycmd2argv(get_ipython_module_path('IPython.terminal.ipapp'))
  
      Parameters
      ----------
      cmd : str
          The command line program to look for.
