Third party libraries

Please keep categories (## level) listed alphabetically and matching their respective folder names. Use two empty lines to separate categories for readability. Subcategories (### level) where needed are separated by a single empty line.

assimp

basis_universal

Files extracted from upstream source:

  • .cpp and .h files in root folder
  • .cpp, .h and .inc files in transcoder/, keeping folder structure
  • LICENSE

bullet

Files extracted from upstream source:

  • src/* apart from CMakeLists.txt and premake4.lua files
  • LICENSE.txt

certs

File extracted from a recent Fedora install: /etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem (It can't be extracted directly from the package, as it's generated on the user's system.)

cvtt

Files extracted from upstream source:

  • all .cpp, .h, and .txt files in ConvectionKernels/

enet

Files extracted from upstream source:

  • all .c files in the main directory (except unix.c win32.c)

  • LICENSE file

Important: enet.h, host.c, protocol.c have been slightly modified to be usable by godot socket implementation and allow IPv6. Apply the patch in the patches/ folder when syncing on newer upstream commits.

Two files (godot.cpp and enet/godot.h) have been added to provide enet socket implementation using Godot classes.

It is still possible to build against a system wide ENet but doing so will limit it's functionality to IPv4 only.
