CGAL users discussion list

[Dror Atariah <>]

I cleared all the previously generated Cmake related files. Then I ran the 
cgal_create_cmake_script and then what you suggested:
> "cmake -DEIGEN3_INCLUDE_DIR=/Users/drorata/Library/eigen3.1.0-rc1 ."

This was the output:

Then trying to compile the example yielded:
---(Output)---

---(Output END)---

This seems not to work.

I don't think that the problem is finding EIGEN. Currently I have (as Michael 
Hemmer suggested) the following line in my CMakeLists.txt:
        include_directories (BEFORE "~/Library/eigen3.1.0-rc1/")

It seems like neither your suggestion nor setting EIGEN3_INC_DIR to the 
eigen's location helps. 

Anyway, with either Michael's trick or Menelaos' (which was adding a soft 
link to the include directory of the example which pointed to the location of 
eigen) it seems like eigen can be found, but the compilation error is always 
there.
