* For Linux and Mac we suggest to link the static exodus library which comes along with libMesh (https://libmesh.github.io/) provided by Moose framework installation:
* Set the EXODUS_LIBMESH variable to `true`
* Define the path to the root directory of the `libmesh` installation using variable LIBMESH
* Alternatively, ExodusII can be installed on Ubuntu/Debian via the system package manager:
```bash
sudo apt install libexodusii-dev
```
Then compile MeshIt with:
```bash
qmake meshit.pro
make -j$(nproc)
```

* For Windows you have to link the dynamic exodus library which will be provided by the package mingw-w64-ucrt-x86_64-libexodus provided by the MSYS2 (https://www.msys2.org/) installation:
* Set the EXODUS_LIBRARY variable to `true`
