How to use an external program with Lualatex and Texmaker?

I do not have too much experience with LaTeX and I would like to configure Texmaker so that LuaLaTeX can use an external program.

In this case, I would like to reproduce a graph (using Gnuplot (which has been added to my path envrironment variable : )) from the documentation of PGFplots:

documentclass[border=10pt]{standalone}
usepackage{pgfplots}

begin{document}
begin{tikzpicture}
    begin{axis}[view={0}{90}]
        addplot3[domain=-2:2, domain y=-1.3:1.3, contour gnuplot={number=14}] 
            {exp(-x^2-y^2)*x};
    end{axis}
end{tikzpicture}
end{document}

But I got the error message:

! Package pgfplots Error: sorry, plot file{"Test"_contourtmp0.table} could not be opened.

After some research on the internet, it seems that LuaLaTeX cannot by default use external programs. So I tried to configure TeXmaker to make this possible, but I don’t think there is such an option, and the TeXmaker manual doesn’t tell me more…

Is it possible to do this with Texmaker?

Note: I don’t know if it matters, but I use the Miktex distribution.

Update

On the advice of Gigiair, I have changed the default command of Texmaker.
