use packageRequirement in shader files

[ahmidou]

compiling using the builtin pipeline gives errors because of the subshaders for universal and HD render pipeline.
you can add PackageRequirements that way in PassesUniversal.hlsl and DearImGui-Procedural.shader to overcome the issue

    // shader for HD render pipeline
    SubShader
    {
        Tags { "RenderType" = "Transparent" "RenderPipeline" = "HDRenderPipeline" "PreviewType" = "Plane" }
        LOD 100

        Lighting Off
        Cull Off ZWrite On ZTest Always
        Blend SrcAlpha OneMinusSrcAlpha

        Pass
        {
            PackageRequirements {
                "com.unity.render-pipelines.high-definition"
            }
            Name "DEARIMGUI HDRP"

            HLSLPROGRAM
            #pragma vertex ImGuiPassVertex
            #pragma fragment ImGuiPassFrag
            #include "./PassesHD.hlsl"
            ENDHLSL
        }
    }

Awesome. That's a must and requested feature.
Thank you
