Hi Alex,

I would prefer to build the source like a normal cmake package,
however Amazon disallows building their SDK anywhere within the
original source directory.  Normally, there should not be any issue
with:

./cmake_pkg_src
./cmake_pkg_src/buildroot-build // PKG_SUPPORTS_IN_SOURCE_BUILD = NO

But in this case there is a cmake rule that iterates over the entire
source directory to check if the build directory is present:
https://github.com/alexa/avs-device-sdk/blob/master/build/cmake/DisallowOutOfSourceBuilds.cmake

Removing the rule from BuildDefaults.cmake gets around this issue.
Also, the source builds perfectly fine this way.  I'm not sure why
Amazon forces this.

Thanks, Matt.
