where does CAST_BUILD_RELEASE come from? I don't see this on the builders.

[byungchul, 2015/01/22 17:47:54]

This will be set by chromecast.mk based on PLATFORM_VERSION in
build/core/version_defaults.mk. I didn't want to describe it here because
version_defaults.mk are not available.

Discussed offline about the issues with this approach.

Let's figure out how to set CAST_BUILD_RELEASE consistently in all of our
downstream builds first.

[byungchul, 2015/01/22 19:46:33]

Changed to read from cast_build_release file which will be set by build env
script.
