This means that the package recipe ``czmq/4.2.0@`` exists, but for some reason
there is no precompiled package for your current settings. Maybe the package creator didn't build
and shared pre-built packages at all and only uploaded the package recipe, or maybe they are only
providing packages for some platforms or compilers. E.g. the package creator built packages
from the recipe for gcc 4.8 and 4.9, but you are using gcc 5.4.
from the recipe for Visual Studio 14 and 15, but you are using Visual Studio 16.

By default, conan doesn't build packages from sources. There are several possibilities:

policy as argument, like ``--build libzmq`` or ``--build missing``. If the package recipe and the source
policy as argument, like ``--build czmq`` or ``--build missing``. If the package recipe and the source
code work for your settings you will have your binaries built locally and ready for use.

- If building from sources fail, you might want to fork the original recipe, improve it until it
