Install and build directory outside of the source tree?

[gshamov]

Hi All,

It would be good to make Itensor to work with standard best practices, that is, to work outside of the source three. PREFIX should be the target installation directory (where you'd put headers and libraries). Not the source directory.

Right now setting PREFIX in options.mk seems to break the build, which is rather gross.

Thanks!

Hi, thanks for the feedback about this. I agree there are some improvements we should make to the build system, and definitely we should change the name of the PREFIX variable to something else so it doesn't conflict with the usual meaning, so we will at least do that.

I do also agree it's a good idea to allow installing libraries and headers outside the source tree (though personally I still like how we default to inside, and I think it's worked well for our users, many of whom are unix novices). So I'll look into that and it should be easy to define a make install target that installs into a PREFIX of the users choosing.

Thanks,
Miles
