conf package:Cabal

Over-ride this hook to get different behavior during configure.
Perform the "./setup configure" action. Returns the .setup-config file.
Try to configure all the known programs that have not yet been configured.
Try to configure a specific program and add it to the program database. If the program is already included in the collection of unconfigured programs, then we use any user-supplied location and arguments. If the program gets configured successfully, it gets added to the configured collection. Note that it is not a failure if the program cannot be configured. It's only a failure if the user supplied a location and the program could not be found at that location. The reason for it not being a failure at this stage is that we don't know up front all the programs we will need, so we try to configure them all. To verify that a program was actually successfully configured use requireProgram.
Try to configure a specific program. If the program is already included in the collection of unconfigured programs then we use any user-supplied location and arguments.
List all configured programs.
Allow depending on private sublibraries. This is used by external tools (like cabal-install) so they can add multiple-public-libraries compatibility to older ghcs by checking visibility externally.
Enable benchmark compilation
explicit CID to be used
Extra arguments to configure
Additional constraints for dependencies.
Enable program coverage
The list of libraries to be included in the hpc coverage report for testsuites run with --enable-coverage. Notably, this list must exclude indefinite libraries and instantiations because HPC does not support backpack (Nov. 2023).
Emit debug info.
The packages depended on which already exist
be as deterministic as possible (e.g., invariant over GHC, database, etc). Used by the test suite
Should we dump available build information on build? Dump build information to disk before attempting to build, tooling can parse these files and use them to compile the source files themselves.
