%description
Nanopb is a small code-size Protocol Buffers implementation in ANSI C. It is
especially suitable for use in microcontrollers, but fits any memory
restricted system.

This package contains the C runtime headers, the static library
(libprotobuf-nanopb.a), the CMake integration files (nanopb-config.cmake) and
the nanopb code generator, which converts .proto definitions into .pb.c/.pb.h
source files.

# %make_build / %make_install run against the in-source Makefile that %cmake
# actually generated, sidestepping the mismatched cmake-macros pair.
