    Trying to figure out why incremental build is not working for larger
    msbuild project but with similar structure as this one.
    
    Here with targets defined as imported targets + separating as scrs/includes
    and repeating scrs in includes  + splitting the test target in BeforeTest,
    CoreTest, AfterTest  .... moving input/outputs test fix the issue   
    
        vsprompt> msbuild testincremental.proj /v:d /t:change
        vsprompt> msbuild testincremental.proj /v:d /t:test
        vsprompt> msbuild testincremental.proj /v:d /t:test
    
    Incremental build now re-work as expected ... need to think if it's correct
    fix or if it's a ms-build issue to act like this ...

Tadin, found why incremental is not working ...
