>From gcc(1): -ffile-prefix-map=old=new [...] Specifying this option is equivalent to specifying all the individual -f*-prefix-map options. This can be used to make reproducible builds that are location independent. Specifically, this additionally enables -fmacro-prefix-map=, which causes prefix mapping to be applied to expansions of __FILE__ and similar macros. Without this option, if source files are compiled by passing the absolute file path to the compiler (as done by e.g. cmake), any expansions of __FILE__ (e.g. from uses of assert()) will contain $srcdir.
