Would you mind quickly sending us the file `detailed.log` that you can
find in the build directory? This would help us a lot.

This implies that the linker (in this case "/usr/bin/ld" was invoked)
was not able to find the library "AtpSigHandler". So, your compiler
toolchain seems to do the right thing by adding
-lAtpSigHandler -lAtpSigHCommData
to the link line but the linker does not know the correct library
location (which would typically be specified by -L<...>). This begs the
question whether "/usr/bin/ld" is actually the correct linker.

It looks like that these two commands might work around the problem by
letting cmake add a "-L<...>" to the command line. You can give this a
shot with the following changes to source/CMakeLists.txt:
diff --git a/source/CMakeLists.txt b/source/CMakeLists.txt
index a6d85d8b68..86ca17d073 100644
--- a/source/CMakeLists.txt

But I would rather prefer to figure out why our cmake configurations
(probably?) selects the wrong linker. In any case, please show us the
full contents of detailed.log
