[LLVMbugs] The rm command can't be running under cmd.exe

[Yonggang Luo (罗勇刚)]

-      COMMAND rm -f *${CMAKE_CXX_OUTPUT_EXTENSION}
+      COMMAND del /Q *${CMAKE_CXX_OUTPUT_EXTENSION}


because rm -f is can be running on -ix system. and msys and cygwin system.
but the problem is rm -f can't be running on windows system.

on windows operating system. only del /Q can be running?

and cmake have a solution to this problem . That's ${RM}


# The command to remove a file.
RM = D:\Tools\cmake\bin\cmake.exe -E remove -f


the cmake submit this variable to resolve this problem.
but i don't know how to use it.
