 Build swig
 ----------
 The required swgi version is 4.1.1. Unfortunately, the ubuntu ppa only provides an outdated 4.0.2 version. If swig 4.1.1 is not available on your machine, you have to download/build by yourself (depends on libpcre2, previously installed):
 ```bash
-$ wget http://prdownloads.sourceforge.net/swig/swig-4.1.1.tar.gz
-$ tar -zxvf swig-4.1.1.tar.gz
-$ cd swig-4.1.1
-$ ./configure && make -j4 && make install

 ```
