# This makefile intends to support building outside the src directory
13
# if desired. When invoking it, specify an argument to SRCDIR on the
14
# command line that points to the top of the directory where your source
23
# Override DESTDIR= on the make install command line to easily support
24
# installing into a temporary location. Example:
26
# make install DESTDIR=/tmp/build/libpng
28
# If you're going to install into a temporary location
29
# via DESTDIR, $(DESTDIR)$(prefix) must already exist before
30
# you execute make install.
34
# To enable assembler optimizations, add '-DPNG_USE_PNGGCCRD' to
35
# $CFLAGS, and include pnggccrd.o in $OBJS, below, and in the dependency
36
# list at the bottom of this makefile.
