0. About CGAL

The Computational Geometry Algorithms Library CGAL build binaries along with the instruction here. For now, this addon uses CGAL of x64 without Qt. For compiling, Boost must be needed. openFrameworks also uses boost. To avoid conflict from difference of version or from duplication, replacing all file of lib in oF directory is recommended. Boost Common but huge template library. CGAL has dependency on it. It may be simpler to download binaries from sourceforge than to build from source by yourself. openFrameworks itself also has the dependency on boost only for file-io which isn't sufficient to compile CGAL.

1. Build your project

Locate CGAL files into ofxCgalUtil\lib\

  lib
    L CGAL-4.14
      L auxiliary
        L gmp
          L include   // locate files in CGAL-4.14\auxiliary\gmp\include
          L lib       // locate files in CGAL-4.14\auxiliary\gmp\lib
      L include       // locate files in CGAL-4.14\include
      L lib           // locate files in CGAL-4.14\lib
      L bin           // locate files in CGAL-4.14\bin
  

Replace boost libs and includes in of_root\libs\boost with files of the same version that you used to build CGAL. Using Project Generator(PG), update your oF project directory. If using Debug mode, you will need to set \bigobj option for compilation since CGAL and boost has so many template functions which will cause exceeding the limitation of .obj files. properties(configuration: Debug) > C/C++ > All Options > Additional Options, type /bigobj.
