Function addPrefixedFileArg [src]

Appends an input file to the command line arguments prepended with a string. For example, a prefix of "-F" will result in the child process seeing something like this: "-Fexample.txt" The child process will see a single argument, even if the prefix has spaces. Modifications to this file will be detected as a cache miss in subsequent builds, causing the child process to be re-executed. Related: addFileArg - same thing but without the prefix addOutputFileArg - for files generated by the child process
