When auto-detection is possible, but an override might be desirable, I
try to mention the choice in the README, and provide an env var for
For example, in my build script for luxrender:
By default, this SlackBuild:
1. Attempts to auto-detect where your Blender install is by grepping
2. Attempts to install the Blender plugin to that location
If you do not want it to attempt to do this, do:
$ BLENDER=no ./luxrender.SlackBuild
The Blender plugin will be copied to /usr/share/luxrender-VERSION
If you do have Blender, but in a different path than the SlackBuild.org
path,, or not
listed in /var/log/packages for some reason, then you can hardcode the path:
$ BLENDER=/path/to/blender/scripts ./luxrender.SlackBuild
