[opus] git snapshots from opus-codec.org website.

[batguano999]

Hi
On the opus-codec web page here ---> http://www.opus-codec.org/development/

Underneath "Source code repository" there are options to download the gits.

As well as the traditional "$ git clone git://git.opus-codec.org/opus.git" there are also Snapshots.
opus-master.tar.gz
opus-1.0.x-branch.tar.gz

It's a great idea...

To download HEAD the command can be like this...
wget "git.xiph.org/?p=opus.git;a=snapshot;h=HEAD;sf=tgz" -qO- | tar -xz; cd opus-HEAD-*; ./autogen.sh

Problem is...
it only brings down the shallow clone.

So when configured it shows...

configure:
------------------------------------------------------------------------
  opus unknown:  Automatic configuration OK.

Then later when we try to compile opus-tools it shows...

checking for OPUS... no
configure: error: Package requirements (opus >= 1.0.3) were not met:

Requested 'opus >= 1.0.3' but version of Opus is unknown
You may find new versions of Opus at http://opus-codec.org/


This problem with shallow clones has been raised before on the mailing list but didn't get fixed.
"Unknown versions in git."
