# On Windows, make's path resolution algorithm is incorrect. It picks up a bazel.exe in PATH that's
# after a bazel binary. In particular, on actions, the non-exe binary is a bazelisk instance, whereas
# bazel.exe is a bazel installation.
# This means we pick up the wrong bazel version, and if the differences between the bazel we want
# and that we actually get are too big, the build fails on CI.
