#
# This makefile downloads, configures and builds Slic3r PE dependencies for Unix.
# (That is, all dependencies except perl + wxWidgets.)
# The libraries are installed in DESTDIR, which you can customize like so:
#
#     DESTDIR=foo/bar make
#
# The default DESTDIR is ~/slic3r-destdir
# If the DESTDIR doesn't exits, the makefile tries to create it
#
# To pass the DESTDIR path along to cmake, set the use CMAKE_PREFIX_PATH variable
# and set it to $DESTDIR/usr/local
#
# You can also customize the NPROC variable in the same way to configure the number
# of cores the build process uses. By default this is set to what the `nproc` command says.
#
