Rather not.  Either put it into your application's directory, then
#include "filename.h" will search it directly there.  Alternatively,
put it into an arbitrary directory, and use the -I compiler switch to
tell the compiler where to look for it.  For Windows, better use
forward slashes as pathname separator in the Makefile, so say

CINCS = -Ic:/where/youve/put/it/to

rather than

CINCS = -IC:\where\youve\put\it\to

as Windows itself recognizes both as a valid pathname separator
internally, but the shell that is called by `make' (which is a Unix
shell) might cause you troubles with the backslashes.  (Optionally,
you might put a space after the -I, but historically, C compilers did
not want a space there.  GCC doesn't care.)

Hint:

#include <something.h>

is meant to be used to search for system header files, while

#include "something.h"

is intented to search for custom/application header files.  (The
difference is that the compiler will never look for a system header
file in the current directory.)
