Bug#1140009: sfcgal: Add support for Eigen in SFCGAL 2.3

[Jean Felder]

Source: sfcgal
Version: 2.2.0-3
Severity: wishlist

Dear Maintainer,

Since version 2.3.0, SFCGAL has introduced an optional dependency on Eigen.
This dependency enables additional simplification strategies in the `surfaceSimplification` algorithm.

It can be enabled at build time using the `SFCGAL_WITH_EIGEN` flag.

Would it be possible to enable this option?

Thanks,
