#
# This CMake project downloads, configures and builds Slic3r PE dependencies on Unix and Windows.
#
# When using this script, it's recommended to perform an out-of-source build using CMake.
#
# All the dependencies are installed in a `destdir` directory in the root of the build directory,
# in a traditional Unix-style prefix structure. The destdir can be used directly by CMake
# when building Slic3r - to do this, set the CMAKE_PREFIX_PATH to ${destdir}/usr/local.
#
# For better clarity of console output, it's recommended to _not_ use a parallelized build
# for the top-level command, ie. use `make -j 1` or `ninja -j 1` to force single-threaded top-level
# build. This doesn't degrade performance as individual dependencies are built in parallel fashion
# if supported by the dependency.
#
# On Windows, architecture (64 vs 32 bits) is judged based on the compiler variant.
# To build dependencies for either 64 or 32 bit OS, use the respective compiler command line.
#
# WARNING: On UNIX platforms wxWidgets hardcode the destdir path into its `wx-conffig` utility,
# therefore, unfortunatelly, the installation cannot be copied/moved elsewhere without re-installing wxWidgets.
