SRC files appearing in the project tree

Hey there,

I am having a weird issue at the moment. I have a build directory with some 3rdparty libs and I can see every SRC directory in the project tree (before was not the case). This is quite annoying to find the main repo when I need to browse for some stuff.

I was wondering if any of you know how to avoid showing SRC directories from the build dir in the project tree? Or there is a way to hide those ones?

Thank you in advance!
