Adding include and library paths when using zig build

[kavika13]

I'm trying to build the Tetris example on Windows. The dependencies (libpng, libepoxy, glfw, etc) are not installed globally on my box, nor do I want them to be.

Should I be modifying build.zig to include the library and header paths? That doesn't seem optimal (unless the tetris project gets modified to include the headers/libs for those inside the project dir, in which case that should be an upstream modification).

Normally you can add additional compiler flags in a build system, but I'm not seeing anything like that in Zig Build. I see -isystem on the compiler itself, but not a way to pass that flag on to it from zig build.

This seems like something that could also be "solved" by a package manager, but we're talking about generic C toolchain compatibility here, so I still think it would be important to support this mode, too.

Sorry if this is an existing ticket. Couldn't find one after like 15 minutes of looking :)

Edit: Seems like there's a lot of related conversation here: #2041

The honest answer here is to sit tight until the package manager (#943) is available.

I see that you mentioned this:

You can expose options to zig build like this:

zig/build.zig

Line 86 in 2c0280b

const test_filter = b.option([]const u8, "test-filter", "Skip tests that do not match filter");

This could be an include path for example.
