Can be built with cmake manually or using
[Qt Creator](https://github.com/qt-creator/qt-creator).
For the build to be successful, I've found through testing on VMs that the system requires around 6GB of RAM.
This is mostly due to the large .obj files that are built into the project using [Qt Resource System](https://doc.qt.io/qt-6/resources.html)
To build and run `qtk` on Ubuntu -
This project has been ported to Qt6, which is not yet available in Ubuntu apt repositories.
To run this project, you will *need* to install [Qt6 Open Source Binaries](https://www.qt.io/download-qt-installer) for your system.
Be sure to take note of the Qt6 installation directory, as we will need it to correctly set our `CMAKE_PREFIX_PATH` in the next steps.
Once Qt6 is installed, to build and run `qtk` on Ubuntu -
```bash
sudo apt update -y && sudo apt install qttools5-dev freeglut3-dev libassimp-dev cmake build-essential
sudo apt update -y && sudo apt install freeglut3-dev libassimp-dev cmake build-essential git
git clone https://gitlab.com/shaunrd0/qtk && cd qtk
mkdir build && cd build
cmake .. && cmake --build .
cmake .. -DCMAKE_PREFIX_PATH=$HOME/Qt6/6.2.3/gcc_64 && cmake --build .
./qtk
```
