<p>In order to develop with OpenGL some system packages are required (unless you are using the N7 machines):</p>
|
||
|
|
<pre><code>sudo apt-get install libglu1-mesa-dev freeglut3-dev build-essential mesa-common-dev libxi-dev libxmu-dev automake</code></pre>
|
||
|
|
<p>To build this code we use the CMake build system. You can install CMake from the system package manager but you need a recent version >= 3.10. Check the version that is provided by your linux distribution and if it is suitable usually you need to</p>
|
||
|
|
<pre><code>```
|
||
|
|
sudo apt-get install cmake
|
||
|
|
```
|
||
|
|
|
||
|
|
otherwise you can install the binaries from here: https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-Linux-x86_64.sh
|
||
|
|
|
||
|
|
To install:
|
||
|
|
```
|
||
|
|
wget https://github.com/Kitware/CMake/releases/download/v3.17.1/cmake-3.17.1-Linux-x86_64.sh
|
||
|
|
chmod +x cmake-3.17.1-Linux-x86_64.sh
|

<p>Also,</p>

<p>builds everything, and</p>
|
||
|
|
<pre><code>make clean</code></pre>
|

<p>cleans everything.</p>
