If I replace lubeck with mir-lapack (which I also installed into 
/usr/local/lib), repeat "meson build && cd build && ninja" and 
call ./demo_proj, I get this:
-----
./demo_proj: error while loading shared libraries: 
subprojects/mir-algorithm/libmir-algorithm.so.3.4.0:ject file: No 
such file or directory

But libmir-algorithm.so.3.4.0 is installed in /usr/local/lib and 
it is in $PATH :(
