# This module will try to located FBX SDK folder, based on the standard
# directory structure proposed by Autodesk.
# On every platform, the module will look for libraries that matches the
# currently selected cmake generator.
# A version can be specified to the find_package function.
#
# Once done, it will define
# FBX_FOUND - System has Fbx SDK installed
# FBX_INCLUDE_DIRS - The Fbx SDK include directories
# FBX_LIBRARIES - The libraries needed to use Fbx SDK
# FBX_LIBRARIES_DEBUG - The libraries needed to use debug Fbx SDK
2023-03-26 11:44:29 +02:00
# FBX_SHARED_LIBRARIES - The shared library file (dll, so) to use Fbx
# FBX_SHARED_LIBRARIES_DEBUG - The shared library file (dll, so) to use debug
# Fbx SDK

# A cmake target named fbx::sdk is also created. Adding this target to your
# project via target_link_libraries will setup everything automatically.

# It accepts the following variables as input:
# FBX_SHARED - Optional. Select whether to use the shared version fbx sdk.
2021-11-11 21:22:24 +01:00
# FBX_MSVC_RT_DLL - Optional. Select whether to use the DLL version or the
# static library version of the Visual C++ runtime library.
# Default is ON (aka, DLL version: /MD).
#
# Known issues:
# - On ALL platforms: If there are multiple FBX SDK version installed, the
# current implementation will select the first one it finds.
# - On MACOS: If there are multiple FBX SDK compiler supported (clang or gcc),
# the current implementation will select the first one it finds.
