[Rcpp-devel] RcppEigen UmfPack?

[Joshua N Pritikin]

A recent post on the Eigen support forum suggests that UmfPack offers 
the best performing sparse LU decomposition,

https://forum.kde.org/viewtopic.php?f=74&t=128919&sid=6498e59768f42c2393dda6c5a5228df4

I tried to include Eigen/UmfPackSupport, but I got

/opt/R/x86_64-pc-linux-gnu-library/3.2/RcppEigen/include/Eigen/UmfPackSupport:9:21: fatal error: umfpack.h: No such file or directory

Can somebody speculate on how much work is involved to get this to 
work?

Thank you.
