[Cmake] Newbie Questions

[Bill Hoffman]

You can specify the compiler and flags with environment variables:
CXX=cxx-compiler
CC=c-compiler
CFLAGS=default-c-flags
CXXFLAGS=default-cxx-flags

This will seed the cache with those values.

We do not directly support asm files, but you could do it with a custom command
and some macros.   Java is supported in this way right now.
It is a bit complicated, but the example is in Modules/CMakeJavaCompiler.cmake.in
Basically, for each .s file you will need an ADD_CUSTOM_COMMAND.
You can do this in a FOREACH, and a MACRO that takes the list of .s files.

Is there an easy way to do this? I am trying to support cross compiling easily (without having to edit every executable line in the cache file). A related question is how can I set some default compiler flags depending on my architecture. I'd like to set defaults for CMAKE_C_FLAGS but these end up being ignored (or at least don't show up in ccmake, I can't remember which). I'd much rather have some basic defaults as opposed to distributing a bunch of cache files. I'd also like these defaults to show up in ccmake so that a user can see what I've set.

I've tried setting up a custom target and custom build commands but I can't figure out how to get my custom target to depend on any of my objects. Again, what should I do here and what is going to be the behavior in the future (1.4.6 vs. 1.6beta1).
