Hi,

Following:

http://cgal-discuss.949826.n4.nabble.com/Tutorial-Patch-cmake-for-visual-studio-and-eigen-or-any-other-platform-and-library-td4479845.html

Windows 7 x64, cgal 4, eigen 3.1.0-alpha2

1. I extracted the contents of the eigen zip into
c:\prj-external-libs\eigen-eigen\ (no installation). This is the main folder
that I also add to my include path, which has the Eigen source dir, i.e.
contains a file: c:\prj-external-libs\eigen-eigen\Eigen\core

2. Using cmake-gui to install cgal, I added a variable (also tried with env
var) EIGEN3_INCLUDE_DIR that is set to c:\prj-external-libs\eigen-eigen\.

3. Pressing on the configure button, I get the following warning:

Configuring demo in
C:/prj-external-libs/CGAL-4.0-x64/demo/Surface_reconstruction_points_3
Could NOT find Eigen3 (missing: EIGEN3_INCLUDE_DIR EIGEN3_VERSION_OK)
(Required is at least version "3.0.91")
