zgt install with zigmod doesn't work

[GoWind]

zig version : 0.10.0-dev.3050+e05487746
OS: 5.3.0-64-generic #58-Ubuntu SMP x86_64 GNU/Linux
zigmod: custom version with a commit on top of zigmod master to fix a breaking change in zig version mentioned above

Following instruction in the README, my zig build ends with the following error

./src/main.zig:6:12: error: container '.zgt' has no member called 'backend'
    try zgt.backend.init();

On closer inspection, it looks like the pkg root of zgt is set to .zigmod/deps/git/github/zenith391/zgt/build_zgt.zig.
Here is the deps.zig entry

pub const _deeztnhr07fk = Package{
        .directory = dirs._deeztnhr07fk,
        .pkg = Pkg{ .name = "zgt", .source = .{ .path = dirs._deeztnhr07fk ++ "/build_zgt.zig" }, .dependencies = null },
        .system_libs = &.{ "gtk+-3.0", "c" },
    };

build_zgt.zig is the main entrypoint in zgt's zigmod.yml file.

If however, I manually tweak this path to point to _deeztnhr07fk ++ "src/main.zig" instead of build_zgt.zig, it works fine. and I get a UI rendered on my desktop.

Did something change in zigmod or zig that broke this behaviour, or is the install fn in build_zgt.zig not supposed to be run, or is it supposed to run using an additional step such as deps.doSomething() ?

I see , commit introduced this change. perhaps this should be src/main.zig ?

Ah yes, I changed the way zgt should be installed. I'll change the instructions on the README very soon.
Meanwhile, like in zgt-template zgt must be added in build_dependencies, for simplicity you can just copy the file to your zigmod.yml.
After running zigmod fetch, add those lines in your build.zig (put them before exe.install()!):

const pathToZgt = ".zigmod/deps/git/github.com/zenith391/zgt/";
try deps.imports.zgt.install(exe, pathToZgt);

And then it should work!

The reason, I changed the way its done is because zgt needs to copy some files and link specific objects when compiling for Windows. Using zigmod's default capabilities it wasn't possible, so I spoke with nektro who suggested this new system.

I need not do this on Linux:

const pathToZgt = ".zigmod/deps/git/github.com/zenith391/zgt/";
try deps.imports.zgt.install(exe, pathToZgt);

Zigmod is emitting the right compiler flags for gtk and C without having to call the install method.
I guess the zgt.install workaround is more for Windows than for Linux at the moment !

Also, the imports struct in deps.zig is empty by default with zigmod

        .directory = dirs._s2cq94y1b4ve,
