Did you try to compile the solution after configuration?
Sebastien.

Thank you for your answer.
Yes, I know, library settings in config is strange. But what shal I do with it?
While configuring CGAL I have:
1. started cmake-gui .. in subdirectory of CGAL-3.8 sources.
2. selected File/Delete Cache
3. pressed Configure two times
4. modified the variables WITH_CGAL_Qt3 - unclicked CMAKE_INSTALL_PREFIX = D:/winappl/CGAL ZLIB_INCLUDE_DIR = D:/winappl/zlib/include ZLIB_INCLUDE_LIBRARY = D:/winappl/zlib/lib/zdll.lib
5. pressed configure once
There were warnings:

The following in your config is strange:
set(CGAL_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_Core_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_ImageIO_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_Qt3_LIBRARY "D:/winappl/CGAL/lib/" )
set(CGAL_Qt4_LIBRARY "D:/winappl/CGAL/lib/" )
it should be path to the library. You should probably clear the cmakecache and try configure it again.
Sebastien.

Hi,
I have probably found the reason of unresolved externals:
While instaling CGAL, I had installed a 64bit version of auxiliary libraries.
After instalation of 32bit version, I can compile my code (on my 64 bit system).
But the warnings remained:
WARNING: Target "example_2" requests linking to directory "D:/winappl/CGAL/lib/". Targets may link only to libraries. CMake is dropping the item.
I will be glad if somebody knows he answer.
Best regards

Hi,
I need to migrate to Win7/VS2010 with CGAL.
I have installed CGAL 3.8 with additional libraries, but I cannot compile anything, not even the CGAL examples.
I have tried two slightly different methods for CGAL compilation - with and without CGAL_AUTOLINK_GMP and CGAL_AUTOLINK_MPFR
Both do not work.
Maybe - could be an error in the variables in the main CGAL configuration file (CGALConfig.cmake in d:\winappl\CGAL\lib\CGAL\ directory?:
set(CGAL_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_Core_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_ImageIO_LIBRARY "D:/winappl/CGAL/lib/")
set(CGAL_Qt3_LIBRARY "D:/winappl/CGAL/lib/" )
set(CGAL_Qt4_LIBRARY "D:/winappl/CGAL/lib/" )
I thought that these variables will be set by the cmake-gui ..
I put CGALConfig.cmake and CMakeCache.txt as attachments...
Thank you for your help - I try to solve this for more than two weks without any light at the end of the tunnel...
Bets regards
Petr
My two trials:
I. CGAL compiled with CGAL_AUTOLINK_GMPand CGAL_AUTOLINK_MPFR unclicked
1. CGAL: CMAKE-GUI ..
* Configure / Generate -- OK
2. D:/winappl/CGAL-3.8/examples/Triangulation_2
* CMAKE-GUI .
o Configure OK
o Generate full of warnings:
WARNING: Target "adding_handles" requests linking to
directory "D:/winappl/CGAL/lib/". Targets may link
only to libraries. CMake is dropping the item.
* Visual Studio 2010
o Build Clean
o Build ALL_BUILD
========= Build: 1 succeeded, 14 failed, 0
up-to-date, 1 skipped =========
- 121 errors - unresolved external - for example:
hierarchy.cpp
2>triangulation_prog1.obj : error LNK2019:

CGAL::Gmpq_rep::~Gmpq_rep(void)"

II. CGAL compiled with CGAL_AUTOLINK_GMPand CGAL_AUTOLINK_MPFR clicked (selected)
1. CGAL: CMAKE-GUI ..
* Configure / Generate -- OK
2. D:/winappl/CGAL-3.8/examples/Triangulation_2
* CMAKE-GUI .
o Configure OK
o Generate OK
* Visual Studio 2010
o Build Clean
+ Build ALL_BUILD
- the same set of 121 errors - unresolved
external - for example:
