Recently I've been trying to compile vxl-beta2 whilst forcing the various v3p
libraries to be used on an irix system, compiling using gcc3.03 I think.
Anyway, I set FORCE_V3P_PNG plus all the other FORCE variables, but it
still doesn't compile those libraries and then at run time complains of
undefined symbols. Do I also need to change the variable that indicates
the location of libpng and png.h? I had originally thought that forcing
v3p could sort that out itself. Doesn't seem to matter what I do though,
those libraries don't get compiled. I checked out the generated Makefile
and it seems that no Targets are being set. Any tips? If not, is there
anyway I can debug the output of CMake so I can at least see why the
Targets aren't being specified? The CMakeLists.txt file seems OK, but it
could be not defining something because of the variables (especially the
ZLIB_FOUND variable, which I also try to force v3p).
