CGAL users discussion list

[杨宝容 <>]

hi, Jiang Luo,
yes, I also have added the inlude and lib path to include directories and 
library directories, but it still doesn't work.

When i compiled CGAL by using Cmake, i also checked both "with_GMP" and 
"with_MPFR". Any other possibility of leading to such a problem?
