Hi there,
Currently the cmaked system doesn't work with Tango. This would be a nice feature to add! I've been trying to hack together tango support myself but I don't know cmake well enough.
Really the only two things that need to happen are gdc needs to be called with "-fversion=Posix", and dmd with "-version=Posix". Then the appropriate library needs to be linked in. With gdc it's libgtango.a, and dmd uses libtango.a.
Also the compiler test needs to be adjusted to use tango.io rather than std. This is another area where I don't know how to properly set it up. I just removed the print statement altogether to it would work on both tango and phobos, but maybe there's a way to detect if you're using tango rather than phobos.
At any rate thanks for cmaked! I'd really like to be using this over dsss, or the other D centric build systems!
