[joejohnston203]

Describe the bug
When installing morpho in a virtual environment, the morpho wheel fails to build. Morpho still seems to run as expected, but this issue should be fixed.

To Reproduce
Follow virtual environment installation instructions in the documentation:

. morpho_venv/bin/activate
pip install -U pip
cd /path/to/morpho
pip install .

Desktop:
Ubuntu 16.04
