Migrate to new cabal build

[IvanMalison]

We get the following message when building:

Warning: The configure command is a part of the legacy v1 style of cabal
usage.

Please switch to using either the new project style and the new-configure
command or the legacy v1-configure alias as new-style projects will become the
default in the next version of cabal-install. Please file a bug if you cannot
replicate a working v1- use case with the new-style commands.
