# On Linux, libcurl needs to know, at compile time, the location for the
# Certificate Authority (CA) bundle file. By default we dynamically guess the
# location for most common Linux distribution, but this guessing makes the build
# not cacheable.
#
# In our CI builds we define the CA bundle location using a --define option.
# This makes the CI results more amenable to caching, at the cost of "some"
# complexity in this BUILD file.
#
# Note that builds issued by developers in the command-line should continue to
# work, it is just that the build results are less cacheable than they make
# wish.

# First convert the --define ca_bundle_style=... option into a config_setting
