Inconsistent output of shared libraries on different operating systems

[KoT3isGood]

Zig Version

0.13.0

Steps to Reproduce and Observed Behavior

I’ve made a really small build system for the library:

const lib = b.addSharedLibrary(.{
  .name = "test",
  .target = target,
  .optimize = optimize,
});
lib.addCSourceFiles(.{
  .files = &.{
  //
  "source/main.c",
  },
});
lib.linkLibC();
const lib_artifact = b.addInstallArtifact(lib, .{});
lib_artifact.dest_dir = .{ .custom = "../lib/" };
b.getInstallStep().dependOn(&lib_artifact.step);

When it gets built on linux using zig build everything gets compiled into lib directory.
When it gets built on windows using the same zig build test.dll and test.pdb get compiled into current working directory. At the same time test.lib is inside of lib directory

Expected Behavior

test.dll and test.pdb should be in the same directory with test.lib

Not a bug. Windows DLLs being installed to <prefix>/bin/ and not <prefix>/lib/ is intentional, see #19743 for details.

To override the PDB, header and DLL import library install dirs you need to set the .pdb_dir, .h_dir and .implib_dir options respectively in the options struct you pass to b.addInstsllArtifact.
