Compilation error: undefined reference to 'cblas_dgemv' / 'cblas_dger' / 'cblas_dgemm'

[p.shkadzko]

I am trying to run example code from 
https://tour.dlang.org/tour/en/dub/lubeck

example.d:
---
/+dub.sdl:
dependency "lubeck" version="~>1.1"
+/
import lubeck: mtimes;
import mir.algorithm.iteration: each;
import mir.ndslice;
import std.stdio: writeln;

void main()
{
     auto n = 5;
     // Magic Square
     auto matrix = n.magic.as!double.slice;
     // [1 1 1 1 1]
     auto vec = 1.repeat(n).as!double.slice;
     // Uses CBLAS for multiplication
     matrix.mtimes(vec).writeln;
     "-----".writeln;
     matrix.mtimes(matrix).byDim!0.each!writeln;
}
---

I try to compile it via:

---
dub build --compiler="ldc" --single example.d -v
---

And get the error below:
