[PD-dev] Use Pd executable to debug an external

[Joseph Larralde]

Hello again,

Stupid me, I had an older version of my external somewhere and it was 
loaded first instead of the freshly built one from CLion.
Now that I deleted the old one I'm able to debug correctly using a local 
build of pd-0.54.0 as the target executable.
Sorry for the noise

Joseph
