Because if you do this then OpenBlas is instantly supported by currently
released versions of CMake. If you are asking for an update to the core of
CMake then you are going to have to wait for the next release of CMake and then
ALL of your users are going to have to update their CMake installations. This
may or may NOT be possible on all those systems. Having used OpenBLAS for a
current project I would like to see the OpenBLAS developers step up and set an
example for the other projects and properly support CMake. Just my 2 cents
worth.
