# Download, unpack and setup Tink dependencies.
#
# Despite the looks, http_archive rules are not purely declarative, and order
# matters. All variables defined before a rule are visible when configuring the
# dependency it declares, and the targets provided by a dependency are visible
# (only) after it has been declared. Following dependencies may rely on targets
# defined by a previous one, for instance on gtest or absl.
#
# Some rules imported from dependencies require small fixes, which are specified
# after the relative http_archive rule. Please always document the intended
# purpose of such statements, and why they are necessary.
#
# In general, when adding a new dependency you should follow this structure:
#
# <set any configuration variable, if any>
# <http_archive for your dependency>
# <define or fix newly imported targets, if any>
#
# Many projects provide switches to disable tests or examples, which you should
# specify, in order to speed up the compilation process.
