CMake is not finding Boost

Question

I am trying to install CGAL. They describe their installation process as ever-so-simple here, section 6.1. When I run cmake-gui and then click configure

Answer 1

I had this error, but I have progressed.

I was using the CMake GUI, ticked the checkbox "Advanced" (between checkbox "Grouped" and button "Add Entry"), and ticked the newly seen checkbox "CGAL_Boost_USE_STATIC_LIBS".

You may need to press "Configure" an extra time or two before the extra options are revealed.
