Help for "Clean" command

[Big dream]

I changed the project. But I can't rebuild the project because the CLEAN command. I found when executing CLEAN command there is error -1073741511. CLEAN command actually executes "rm -f -r". But my platform is win7. Is "rm" used in powershell? Maybe it needs to be changed to "del". But how to change it? Where to set it up in codelite?
