# - coqide compilation can be disabled by setting buildIde to false
# - The csdp program used for the Micromega tactic is statically referenced.
#   However, coq can build without csdp by setting it to null.
#   In this case some Micromega tactics will search the user's path for the csdp program and will fail if it is not found.
# - The exact version can be specified through the `version` argument to
#   the derivation; it defaults to the latest stable version.
