16 # if desired. When invoking it, specify an argument to SRCDIR on the
17 # command line that points to the top of the directory where your source
26 # Override DESTDIR= on the make install command line to easily support
27 # installing into a temporary location. Example:
29 # make install DESTDIR=/tmp/build/libpng
31 # If you're going to install into a temporary location
32 # via DESTDIR, $(DESTDIR)$(prefix) must already exist before
33 # you execute make install.
