Hi,

Configuring BLAS, LAPACK and TAUCS with cmake-gui is feasible but complex.
Let's try first an easier solution.

Please define the environment variables:
BLAS_LIB_DIR=path to BLAS libraries
LAPACK_LIB_DIR=path to LAPACK libraries
TAUCS_INC_DIR=path to TAUCS headers
TAUCS_LIB_DIR=path to TAUCS libraries

Then remove CMakeCache.txt and run again CMake in 
examples/Surface_reconstruction_points_3/.

Regards,
Laurent S.
