Because I don't want just the default source of EtherCAT built into the
Linux image.  Lets say I want to modify something in the examples directory
of EtherCAT.  For instance, I had to modify the sample code and rebuild.  So
what I want is this "rebuilt" version of EtherCAT, with customized example
code, as part of the Linux image.  If I point at the EtherCAT website, that
won't be the correct version.  The EtherCAT examples development will occur
on the same machine that Buildroot is on, hence why I like the local
filesystem solution.

So any thoughts on why it is not finding the file?

Thanks.
