Freeze version of external dependencies
Freeze version of external dependencies

Recently, an error during build time was introduced because one external
dlux dependencies has been updated. In the version resolving tool, the
extracted library was always the latest. To avoid other similar issues,
all libraries must need to be resolved according to the public API used
and not using "latest" or "master". According to semantic versioning,
those values allow the versioning tool to fetch library version with a
different API.
