# Notes:
#  - The VS2017 build is disabled (commented out) below, as we build both VS2015 and VS2017
#    on Azure Pipelines instead, since that is much faster.
#
#  - For the Cygwin build, the CYG_MIRROR URL used to use the "Cygwin Time Machine" archive
#    in order to pull a previous version of Cygwin, v2.11.2-1 (with timestamp 1550062412).
#    This was done as version 3 had issues and didn't build at all.
#    The previous URL was:
#      http://ctm.crouchingtigerhiddenfruitbat.org/pub/cygwin/circa/64bit/2019/02/13/045332
#
#    In order to speed the builds up we use the "-X" or "--no-verify" option to skip checking
#    the signatures on packages.
