Summary:                    ExternalProject_Add: please support python setup.py
style of install
Description: 
Many python extensions are installed by relying on a distutils scheme. They ship
with a Python script setup.py and the installation proceeds with python setup.py
install in the simplest case. The most general scheme is a two-step process:
python setup.py build [options] (or build_ext instead) and then python setup.py
install [options]. Performing the latter without options always does the right
thing.

It would be nice if ExternalProject_Add supported new arguments to set it up out
of the box. 
I propose the following:

ExternalProject_Add(
...
  PYTHON_SETUP 1    # switch distutils style of installing on/off
  PYTHON_EXECUTABLE path # which Python interpreter to use 
                                            # default: ${PYTHON_EXECUTABLE} as
found by FindPython
  PYTHON_BUILD_COMMAND    # arguments passed to python setup.py for the build
stage
                                                # default: build
  PYTHON_INSTALL_COMMAND # arguments passed to python setup.py for the install
stage
                                                 # default: install
)
