[QUESTION] Ubuntu 14.04 Compatibility

Bug description

I am unable to compile at Ubuntu 14.04 due to minimum cmake version requirement.

Hotfix:

It was quite simple to solve. I just changed from 3.4 to 2.8 as show bellow and worked just fine.

CMAKE_MINIMUM_REQUIRED(VERSION 3.4)

To

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)

Then I tested using travis for manual compilation with something like:

language: generic
matrix:
  include:
  - name: "Trusty indigo"
    dist: trusty
  - name: "Trusty jade"
    dist: trusty
  - name: "Xenial kinetic"
    dist: xenial

before_script:
  - sudo apt-get install -y cmake libeigen3-dev # DQRobotics

script:
  - mkdir build
  - cd build
  - cmake ..
  - make

To ensure it would not have any trouble.

Environment:

OS: [Ubuntu 14.04, ,Ubuntu 16.04, Ubuntu 18.04]
dqrobotics current

Thanks for the report.

Ubuntu 14.04 reached its end of life a couple of months ago on April 2019.

This means we don't support it anymore and probably you shouldn't be using it as well. Is there any specific reason why you need trusty?
