man patch
-pnum or --strip=num
Strip the smallest prefix containing num leading slashes from each file name found in the patch file.
A sequence of one or more adjacent slashes is counted as a single slash. This controls how file names
found in the patch file are treated, in case you keep your files in a different directory than the
person who sent out the patch. For example, supposing the file name in the patch file was

/u/howard/src/blurfl/blurfl.c

setting -p0 gives the entire file name unmodified, -p1 gives

u/howard/src/blurfl/blurfl.c

without the leading slash, -p4 gives

blurfl/blurfl.c

and not specifying -p at all just gives you blurfl.c. Whatever you end up with is looked for either
in the current directory, or the directory specified by the -d option.
