I haven't a clue. I just tried it and it worked fine.
To the impl.cc file, I added:
#include <gnuradio/blocks/pdu.h>
...
gr::blocks::pdu::vector_type i = gr::blocks::pdu::float_t;
size_t t = gr::blocks::pdu::itemsize(i);
And then I added BLOCKS to the GR_REQUIRED_COMPONENTS and it worked fine.
Without the cmake changes, I get the same error, but otherwise, it worked
as expected here.
