Hi Thibault,

On Windows, CGAL searches for LAPACK in P:/ath/to/TAUCS/auxiliary/taucs.
Please post the content of this folder on your PC.

LAPACK should be detected at CMake stage.
Please run again CMake in e.g.  jet_smoothing_example's folder and post 
its output
(I recommend you do use cmake-gui to see CMake's output).

Best regards,
Laurent Saboret
