cmMakefile: Refactor AddCMakeDependFile  and AddCMakeOutputFile.

AddCMakeDependFile and AddCMakeOutputFile both store as std::string
and all calling sites use std::string. So instead of creating more
temporary objects, lets just use std::strings.

cmMakefile: Track configured files so we can regenerate them.

Currently when a configured file is removed from the build directory,
running the build command will not regenerate the file. Now detect
this and will rerun cmake properly when a user issues the build
command.
