Checking native dependency library is installed in Python setup.py <p>I have a python application that requires a specific C library to be installed on the machine to build properly (usually installed via <code>sudo yum install xxx</code> or <code>sudo apt-get install xxx</code>).</p> <p>Is there a way to verify that those packages are already installed from within setuptools and if not, prompt the user to install them?</p>
