Writing Nix expressions for Qt libraries and applications is largely similar as for other C++ software.
This section assumes some knowledge of the latter.
However, Qt makes extensive use of runtime dependency detection.
In nixpkgs, those runtime dependencies are made into build dependencies through wrappers.
The major caveat with Qt applications is that Qt uses a plugin system to load additional modules at runtime,
from a list of well-known locations. In Nixpkgs, we patch QtCore to instead use an environment variable,
and wrap Qt applications to set it to the right paths. This effectively makes the runtime dependencies
pure and explicit at build-time, at the cost of introducing an extra indirection.
