[CMake] Issues with CMake + TAU

[sindimo]

The wrapper scripts aren't ours, they are part of the TAU profiler tool
from the University of Oregon, so it's not something we would like to edit
or mingle with.



As a workaround I've implemented a custom command that runs post build
which does the job, I'll post it here if anyone else is having the same
issue:



################################

if(UNIX)



#Cleanup TAU temp files



    add_custom_command(TARGET  myApp.exe



      POST_BUILD



      #Move TAU temp files to output folder

      COMMAND  mv

      ARGS     -f *.pp.* ${LIBRARY_OUTPUT_PATH}



      COMMENT  "Cleaning TAU temp files"

    )



endif(UNIX)

################################



The only issue with this is that if I cancel the build intentionally while
it's taking place (e.g. CTRL+C) or the build fails for whatever reason, the
TAU temp files will remain in the current directory since the clean up only
happens after a successful post build.



If anyone has any better ideas please let me know.



I came across this document online and it mentions patching CMake to work
better with TAU, I am guessing this is not official from CMake, but maybe
worth thinking of to add new CMake TAU variables:
