[Sound-open-firmware] help with unit tests

[kalamara at ceid.upatras.gr]

Hello, this is the first post from a newb user so first of all kudos to 
everyone for this amazing project.

I have followed the build from scratch instructions and built 
successfully the apl firmware (from branch master),
but am having trouble building the unit tests:


:~/lara/sof/sof/build_ut$ cmake -DTOOLCHAIN=xtensa-apl-elf 
-DROOT_DIR=`pwd`/../../xtensa-root/xtensa-apl-elf  -DBUILD_UNIT_TESTS=ON

It seems something that should be obvious is missing from my setup, even 
though i am able to build SOF binaries?
Can you please advise?

my environment is

Ubuntu 18.04.1 LTS
cmake version 3.10.2

regards and thanks
