Hi there

I'm having problems trying to configure CGAL for Visual Studio 2005 
using Cmake and I have a few questions regarding environment variables 
and paths relating to the errors. I got gmp building but not mpfr.

GMP
I have set GMP_INCLUDE_DIR in one of CGAL's subfolders as can be seen, 
but there are no files in either of gmp or taucs  include and lib 
subfolders in CGAL-3.4/auxiliary! I called ./configure and make so now I 
have libgmp.la and libgmp.lai in the .libs folder that's created.

MPFR
I have mpfr-2.4.1. There is no include directory in it, nor a lib 
directory, so what should MPFR_LIBRARIES_DIR be set to? As can be seen, 
I have set MPFR_INCLUDE_DIR to C:/prog/mpfr-2.4.1 but I'm not sure if 
this is correct. I call
./configure --with-gmp=c:/prog/gmp-4.2.4

I have created c:/prog/gmp-4.2.4/include and copied the header files 
already in  c:/prog/gmp-4.2.4 into it.
I also created c:/prog/gmp-4.2.4/lib and copied libgmp.la and libgmp.lai 
into it. This seemed to fix the problem of finding the headers and lib 
files but I still get one more error that stops the build. Here's the 
last few lines from calling configure

checking for recent GMP... yes
checking for gmp internal files... yes
checking for valid BITS_PER_MP_LIMB and BYTES_PER_MP_LIMB... yes
checking for __gmpz_init in -lgmp... no
configure: error: libgmp not found or uses a different ABI.
Please read the INSTALL file -- see "In case of problem".

Appreciate any help, I can't for the life of me, undrstand why libgmp is 
not found. I'm using Windows Vista on a 32-bit machine and 
c:/prog/gmp-4.2.4 is in the Path.

Thanks
