You can change the location where nextpnr will be installed (this will usually default to `/usr/local`) by using
`-DCMAKE_INSTALL_PREFIX=/install/prefix`.
It is possible to pre-generate `.bba` files. This can come in handy when building on time-constrained cloud
instances, or in situations where python is unable to use modules. To do this, specify the path to pre-
generated `.bba` files by passing `-DPREGENERATED_BBA_PATH=` to cmake.
