DUNE_PYTHON_VIRTUALENV_SETUP

Set this variable to allow the Dune build system to set up a virtualenv at configure time. Such virtual environment is very useful, whenever python code is to be run at configure time, i.e. to implement code generation in Python or to use Python wrappers in testing. Some downstream modules will require you to set this variable. When setting this variable, you allow the Dune buildsystem to install packages through pip into a virtualenv, that resides in a cmake build directory. For all the information on this virtualenv, see DunePythonVirtualenv.
