Add zigmod.yml

[jitjack]

If you get the time, would it be possible to push your zigmod.yml (or add the various C lib folders as git submodules)?

E.g. from the ./rcutils/build.zig:

FileNotFoundError: [Errno 2] No such file or directory: '.zig-cache/o/e5340387779629e2f67de3091701691f/include/r
cutils/logging_macros.h'
error: the following command exited with error code 1:
cd ~/.cache/zig/p/N-V-__8AAOqPDQCP7E4N6LwRxUvQSKSZHzshqQi4Usv939E- && python3 -c import sys
for arg in sys.argv:
    if arg.startswith("-P"):
        sys.path.append(arg.lstrip("-P"))
import em
output = sys.argv[-1]
em.invoke(['-o', output, '-D', 'rcutils_module_path="./"', 'resource/logging_macros.h.em']) .zig-cache/o/e534038
7779629e2f67de3091701691f/include/rcutils/logging_macros.h 

Also, it's not a big deal, but maybe add an option to the root build.zig to pass system-python to zigros, so this doesn't have to be hardcoded, e.g.:

const zigros = ZigRos.init(b.dependency("zigros", .{
        .target = target,
        .optimize = optimize,
        .@"system-python" = true,
    })) orelse return;

Great project! I would love to be able to write ROS nodes in Zig :)

I'm not using zigmod, this should build with the normal zig package manager out of the box. Logging macros is generated by that python code that is also failing, so it'd make sense that its not found. Can you run with system python set to false? Do you still see the error? This is the main supported methodology as then the environment is fully defined by the zig build. Can you also run the failed command as reported there? you should get more info as to why it failed, for example run this by hand:

cd ~/.cache/zig/p/N-V-__8AAOqPDQCP7E4N6LwRxUvQSKSZHzshqQi4Usv939E- && python3 -c "import sys
for arg in sys.argv:
    if arg.startswith("-P"):
        sys.path.append(arg.lstrip("-P"))
import em
output = sys.argv[-1]
em.invoke(['-o', output, '-D', 'rcutils_module_path="./"', 'resource/logging_macros.h.em'])" .zig-cache/o/e534038
7779629e2f67de3091701691f/include/rcutils/logging_macros.h 

I just tested the main branch in a clean environment and could not reproduce this issue. Using system python I suspect is what's causing issues, though re running that command by hand should reveal all.

Thanks for checking out the project! Preliminary service support should be coming some time this week.
