%description
libigl is a simple C++ geometry-processing library. The header-only core covers
discrete differential geometry, mesh I/O, parametrization, deformation, and a
broad set of linear-algebra / mesh utilities on top of Eigen. (The optional
modules that wrap CoMISo, Embree, CGAL, tetgen, etc. are not built here; only the
header-only library is shipped.)

# Header-only: nothing to compile (the upstream CMake build would download
# optional external modules at configure time, which we deliberately skip).
