# TODO(absl-team): This script isn't fully hermetic because
# -DABSL_USE_GOOGLETEST_HEAD=ON means that this script isn't pinned to a fixed
# version of GoogleTest. This means that an upstream change to GoogleTest could
# break this test. Fix this by allowing this script to pin to a known-good
# version of GoogleTest.
