Your project was successfully created!

Then I made a simple early version of the inner loop, and:

$ mkdir build
$ cd build
$ cmake .. -DCMAKE_BUILD_TYPE=ReleaseWithDebInfo
CMake Warning at cmake_modules/SuperColliderServerPlugin.cmake:10 (message):

  to the folder containing this CMakeLists.txt file

-- Configuring incomplete, errors occurred!

I will, of course, set the path manually... but... what was the point of specifying the path during the questionnaire? It's right there: full_path_to_supercollider_source: /home/dlm/share/supercollider/ -- I did provide the information to the script, but then the script seems not to have done the right thing with it.
