Details

The Eigen package does not ship the cmake files (FindEigen3.cmake etc) included in the source tarball (in the subdirectory 'cmake').

This is probably because `make install` does not install them. I guess Eigen expects packagers to install them to the proper location manually.

Either way, there are projects that expect these files to be installed along with Eigen. Those currently fail to configure on Arch.
This task depends upon

For reference Fedora, Gentoo and Ubuntu all ship atleast FindEigen3.cmake . I don't believe they ship the rest of the cmake files.

Has this been reported upstream? I find it hard to believe that they expect packagers to install this file manually.

I'll have a look at their bugtracker and if not report it there too. In the mean time though it would be really nice to have it installed by the PKGBUILD. That is what many other distros are doing (the equivalent of, at any rate).

Couldn't find it, so new issue added on the Eigen bugtracker: http://eigen.tuxfamily.org/bz/show_bug.cgi?id=1219

Response from upstream is that FindEigen3.cmake shouldn't be installed globally. The current development version of eigen installs a Eigen3Config.cmake instead, which will also work for other projects doing `find_package(Eigen3)`.

So what to do in the mean time? Wait it out until 3.3 (I don't know how long that will take), or install FindEigen3.cmake anyway?
