[Bf-committers] building the bmesh branch

[Michael McLay]

The bmesh branch will not build using scons. The problem has to do with
library linking order when building the blender executable. The files
source/blender/modifiers/intern/MOD_mirror.c  and
source/blender/modifiers/intern/MOD_array.c call CDDM_To_BMesh(dm, NULL),
which is located in the
bf_blenkernel.a library. Since this library is linked before the library
containing the object files from MOD_array.c and MOD_mirror.c the name
CDDM_To_BMesh is never resolved. Adding bf_blenkernel.a to the end of the
list of libraries passed into BlenderProg in SConstruct fixes the linking
problem. There's probably a more elegant way to do this, but at least this
makes it possible to build the bmesh version of Blender.
