Support for launching matlab via CMake in setup-matlab@v2 about setup-matlab

[mcafaro]

Interested to hear if you end up getting things working with v2.

Hi @traversaro, like #89, we do not have an official solution for supporting this type of workflow yet.

In the meantime, you may be able to create an adapter script that translates the matlab command CMake is attempting to call into a run-matlab-command call.

For example, in your job log, I see CMake is attempting to call matlab -nodisplay -nodesktop -nojvm -batch SOME_COMMAND_HERE. You could potentially write a bash script named matlab that does something like this:

# Example: 
# matlab -nodisplay -nojvm -batch "disp hello"

# Treat the last arg as the command
# In the example: "disp hello"
cmd=${@: -1}

# Treat everything else but the last two args as args for run-matlab-command 
# In the example: -nodisplay -nojvm
args=${@:1:$#-2}

# Call run-matlab-command with the cmd and args
# In the example: ./run-matlab-command "disp hello" -nodisplay -nojvm 
run-matlab-command "$cmd" "$args"

Then you have to get CMake to call your version of matlab instead of the matlab in the MATLAB bin folder. I am not familiar enough with the FindMatlab module to know if it supports doing that.

Like I mentioned in #89 though: please note the "run-matlab-command" binary is undocumented and subject to change in the future.

Good idea, thanks! I was thinking on modifying the CMake build system to use run-matlab-command, but avoiding to modify the CMake script would be welcome.

Sure, thanks!
