title: Install conda package to the system, and not an environment
body: <p>I want to install a package, that's only available via conda (that's the only reason I have to use conda); I don't need or can't use a virtual environment. Is there a way to <code>conda install package</code> to the system, without any virtual environment, and then have the said package available sytemwide (as if it was installed via pip)?</p>
  <p>Alternatively, is there an equivalent of <code>python setup.py build</code> for Conda? That'd allow me to build the package at least and I can use it locally.</p>
  <p>Thanks!</p>
