There may be a way to do this "automagically" but the simplest and most
direct approach I can think of is to take advantage of the fact that cmake
prefers out-of-source build and just build twice, the first time building
for the host system, then building for the target system, but allowing the
use of the codebook generator binary from the host system with a cmake
option.
Something like:
$ svn co https://freetel.svn.sourceforge.net/svnroot/freetel/codec2-dev
$ mkdir codec2-host codec2-arm
$ cd codec2-host
$ cmake ../codec2-dev
$ make
$ cd ../codec2-arm
$ cmake -DGENERATE_CODEBOOK_BIN=../codec2-host/src/generate_codebook
../codec2-dev
$ make
