As we never attempted to do any sort of CMake generator, not even

one for Tup from you guys. Anyone that would like to help with this
task?
I think it would be a somewhat larger undertaking. It may tax tup quite a
bit. However, CMake has a pretty good set of tests so you would know when
it was working.
I'm not too familiar with CMake, but I wrote tup. What part of making
a CMake generator do you think would tax tup?
Not sure yet, perhaps none of it. It would have to build custom
commands and targets. Basically, support for code generators like
swig/moc/lex/yacc. I guess the auto-depend stuff in tup would work for
C/C++, but the Fortran 90 stuff in CMake would not work. It would be an
interesting project. To be honest I really did not research tup very
much at all. CMake is also used to build very large projects like KDE,
sounds like tup is designed with that in mind, but it would have to
handle very larger numbers of targets and .o files.
Would tup support the idea of building .o files with -j 5, and linking
executables with -j 2 say? Some targets are more expensive than others,
and you want to limit parallelism sometimes. Note, the makefiles in
CMake do NOT do this now, it would be a nice feature.
