This is a CentOS 7.6 node with EB 4.1.1. I'm trying to build R-3.6.2.

octave-3.8.2-20.el7.x86_64 is installed on the build node.

[verdurin]

Build succeeds on a VM without octave.

Bug is caused by a broken FindOctave script: stevengj/nlopt#314

[Flamefire]

Fixed by them for their next release. Still: Probably best to create an EasyBlock to set ALL of https://github.com/stevengj/nlopt/blob/master/CMakeLists.txt#L43-L47 depending on whether they are actual dependencies
