# 20220420 bkw: Modified by SlackBuilds.org, BUILD=2:
# - move docs to proper Slackware doc dir.

# 20220214 bkw: Modified by SlackBuilds.org again: ogre-13.2.4 really
# wants imgui-1.85 (not 1.86; it was failing to build with that). Also,
# we can use assimp now, so get rid of -DOGRE_BUILD_PLUGIN_ASSIMP=FALSE.
# It will be autodetected, the build will succeed with or without it.

# 20210215 bkw: modified by SlackBuilds.org: force-disable the assimp
# plugin. Our assimp is too old (or too new?) for this version of
# ogre. This allows ogre to be built on a system where assimp is
# installed.
