Setting up a new Linux VM, Yet another build problem. Posting this in case a) it helps anyone else, b) maybe I did something wrong.
I installed Ubuntu 16.04 LTS. Followed the instructions in the VCV manual to build.
When I got to
make dep it failed making RTAudio. Said I had cmake 3.5, but needed at least 3.10.
Since 3.5 is the version of cmake that goes with 16.04, I had to download and build cmake. It wouldn’t build, however, because it couldn’t find SSL. so
sudo apt install openssl-dev.
Now everything is fine.
There is an issue open with rtadudio on this. But your workaround is useful, thank you. https://github.com/thestk/rtaudio/pull/200#issuecomment-589794837
In this case it helps just to change manually the
cmake_minimum_required version back to 3.5 or 3.0 in the downloaded CMakeLists.txt.
Or just install and use a recent prebuilt linux version of CMake from https://cmake.org/download, like https://github.com/Kitware/CMake/releases/download/v3.16.4/cmake-3.16.4-Linux-x86_64.sh for instance. (As far as I understand the post you built CMake from the sources )
