Function dependencyFromBuildZig [src]

Prototype

pub fn dependencyFromBuildZig( b: *Build, comptime build_zig: type, args: anytype, ) *Dependency

Parameters

b: *Build

build_zig: typeThe build.zig struct of the dependency, normally obtained by @import of the dependency.
If called from the build.zig file itself, use @This to obtain a reference to the struct.
