Description
Build log attached, it fails with clang 3.9 clang 5.0 and gcc 6.5 (even my patched gcc6 which has fixed math headers).
Lots of warnings, but the issues seems to be: opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_devel_cmake/cmake/work/cmake-3.14.5/Source/cmFileCommand.cxx:2615:66: error: call of overloaded 'lround(double)' is ambiguous
this->CurrentPercentage = std::lround(value / total * 100.0);
