I don't see any compiler errors. I see warnings and if they built with -Werror,
then it would fail.

I think there is a way to force a cmake build to show the command invoked. This
has lots of details:

https://stackoverflow.com/questions/2670121/using-cmake-with-gnu-make-how-can-i-see-the-exact-commands

I think you can manually go down into the build directory which is left
after the build failure, and type "make VERBOSE=1" >ida.log 2>&1"

Then the file ida.log should show all the commands.

The URL above shows how to do it via cmake. But in this case, I think
going into the RSB build/ directory and doing the make by hand will
give us the next bit of into -- does it compile with -Werror.
