[graph-tool] CGAL library not found (though installed)

I installed CGAL from source and it installed at /usr/local/include/CGAL/ Then when I try to build graph-tools (both 2.26 and the source from git) give me CGAl not found error. They do seem to be checking in the /usr/local directory but don't seem to find it..I have attached a log. Is there something I should keep in mind while installing CGAL ?
