FindNanopb.cmake pb_common.c, pb_decode.c and pb_encode.c marked for cleanup during ninja clean #1104
Description
When using the "traditional variables" version of NANOPB_GENERATE_CPP, the non-generated source files in NanoPB get clobbered on a ninja clean. My workaround was to remove them from the NANOPB_SRCS list after find_package() statement and then add them back manually to our targets using target_sources() after our NANOPB_GENERATE_CPP statements.
