QtWebEngine/Qt5Build

Install build dependencies

QtWebEngine 5.x series require Python 2.7 which is not longer supported, therefore the easy way to obtain it is use pyenv.

brew install pyenv
pyenv install -l
pyenv install 2.7.18
pyenv global 2.7.18
pyenv init --path
export PATH="/Users/qt/.pyenv/shims:${PATH}"
ulimit -n 1200
