#
# 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.
#

# Note: libcurl build system seems to be a bit wonky about finding openssl (cf. #2378).
# It seems that currently the only working option is to set a prefix in the openssl build
# and use the `--with-ssl=...` option in libcurl.
# Additionally, pkg-config needs to be installed and openssl libs need to NOT be installed on the build system.
