[brlcad-devel] Trunk build fails with invalid lemon command line

[Simon F. <sim...@hi...>]

My attempts to build brl-cad from trunk are failing with an invalid
lemon command line - here's the relevant snippet from the build log:

cd /home/sjjf/software/brl-cad/brlcad-build/src/libgcv/plugins/obj/wfobj/WFOBJ_PARSER_obj_grammar && /usr/bin/lemon -T /home/sjjf/software/brl-cad/brlcad-build/src/libgcv/plugins/obj/wfobj/WFOBJ_PARSER_obj_grammar/obj_grammar.yy
src/libgcv/plugins/obj/wfobj/CMakeFiles/libwfobj.dir/build.make:74: recipe for target 'src/libgcv/plugins/obj/wfobj/WFOBJ_PARSER_obj_grammar/obj_grammar.out' failed

The -T option to lemon needs an argument pointing at the lemon
parser template (normally /usr/share/lemon/lempar.c), and it's
failing without that. I can't figure out the CMake config that's
producing that pattern - I'm hoping someone more familiar with the
build system can see the problem right away.
