Hello,

Thanks for your suggestions. They solved the problems related to the .lib files.

I tried the alternatives you suggested.
1)setting BLAS_INC_DIR and BLAS_LIB_DIR as environment variables using the binaries from netlib.org, but it gave the same error 
  "LINK : fatal error LNK1104: cannot open file 'libcblas.lib"
2) Tried your precompiled libraries LAPACK/BLAS/TAUCS and got lipcblas.lib,
    but got another error : "cannot open vcf2c.lib"(i forgot the error number)
   Downloaded vcf2c.lib and put it in CGAL-3.8\auxiliary\taucs\include directory and compiled it again , but got the following error:
   
2>jet_smoothing_example.obj : error LNK2019: unresolved external symbol _dgelss_ referenced in function "void __cdecl CGAL::LAPACK::dgelss(int *,int *,int *,double *,int *,double *,int *,double *,double *,int *,double *,int *,int *)" (?dgelss@LAPACK@CGAL@@YAXPAH00PAN010110100@Z) 
2>C:\Users\Subha\Desktop\CGAL-3.8\examples\Point_set_processing_3\Debug\jet_smoothing_example.exe : fatal error LNK1120: 1 unresolved externals

I followed one of your earlier suggestions to Laurent Saboret(on Fri, 29 Jan 2010)  
 for the same query and added #define CGAL_LIB_DIAGNOSTIC at the beginning of e.g. jet_smoothing_example.cpp, and compiled.

The error still persists and the list of errors is as  follows :

2>jet_smoothing_example.obj : error LNK2019: unresolved external symbol _dgelss_ referenced in function "void __cdecl CGAL::LAPACK::dgelss(int *,int *,int *,double *,int *,double *,int *,double *,double *,int *,double *,int *,int *)" (?dgelss@LAPACK@CGAL@@YAXPAH00PAN010110100@Z)
2>C:\Users\Subha\Desktop\CGAL-3.8\examples\Point_set_processing_3\Debug\jet_smoothing_example.exe : fatal error LNK1120: 1 unresolved externals
1>normal_estimation.obj : error LNK2019: unresolved external symbol _dgelss_ referenced in function "void __cdecl CGAL::LAPACK::dgelss(int *,int *,int *,double *,int *,double *,int *,double *,double *,int *,double *,int *,int *)" (?dgelss@LAPACK@CGAL@@YAXPAH00PAN010110100@Z)
1>C:\Users\Subha\Desktop\CGAL-3.8\examples\Point_set_processing_3\Debug\normal_estimation.exe : fatal error LNK1120: 1 unresolved externals.

Anticipating your valuable suggestions,

Subhasree.

Probably you did not setup the CMake configuration correctly.

If you want to avoid to do that yourself, you can relaunch the CGAL Windows
installer, and ask it to download our precompiled LAPACK/BLAS/TAUCS libraries.
Then re-run cmake for Point_set_processing_3 from an empty cache. That time it
will find BLAS automatically.

If you really want to use the binaries from netlib.org, then you probably need
to define BLAS_INC_DIR and BLAS_LIB_DIR in your environment variables.
