How to skip target including dependencies?

[Danielku15]

Is it possible to get Nuke skipping dependent targets if they are not needed for execution? It seems OnlyWhenStatic (with or without WhenSkipped) has no effect on the dependent targets.

I followed the docs of the Conditional Execution with Static Conditions and have a setup comparable to this:

public static int Main() => Execute<Build>();

Target PrepareForBuild => _ => _
    .Executes(() =>
    {
        Log.Information("Long running task");
    });

bool HasCompileOutputs => true;
Target Compile => _ => _
    .OnlyWhenStatic(() => !HasCompileOutputs)
    .WhenSkipped(DependencyBehavior.Skip)
    .DependsOn(PrepareForBuild)
    .Executes(() =>
    {
        Log.Information("Compiling Main App");
    });

Target CompileTests =>  _ => _
    .DependsOn(PrepareForBuild)
    .Executes(() =>
    {
        Log.Information("Compiling Tests");
    });

When I run build.cmd CompileTests I correctly get:

╬════════════════════
║ PrepareForBuild
╬═══════════

14:49:47 [INF] Long running task

╬═════════════════
║ CompileTests
╬════════

14:49:47 [INF] Compiling Tests

═══════════════════════════════════════
Target             Status      Duration
───────────────────────────────────────
PrepareForBuild    Succeeded     < 1sec
CompileTests       Succeeded     < 1sec
───────────────────────────────────────
Total                            < 1sec

But when I run build.cmd Compile I get:

╬════════════════════
║ PrepareForBuild
╬═══════════

14:49:03 [INF] Long running task

═══════════════════════════════════════
Target             Status      Duration
───────────────────────────────────────
PrepareForBuild    Succeeded     < 1sec
Compile            Skipped                // OnlyWhen: !HasCompileOutputs
───────────────────────────────────────
Total                            < 1sec

I want also PrepareForBuild to be skipped because no target requires it. Is this possible with Nuke? Of course I could move the logic into own methods an call the custom sequence, but then I lose all the features of Nuke like collapsible logs, time measurement etc. I want to avoid that.

I found the discussion around calling targets manually which would also solve my case. But there was no real solution there which solves my task. #119

In my real setup I cache some build outputs using GitHub actions and I want to dynamically check if I can use those cached files. There are cases where I use the cached files and don't compile and cases where I decide recompilation is needed.
