rgetz · pcercuei · commit bde61deac34f · 2023-05-11T14:14:39.000+01:00

Cmake 2.8.12 was released Tue Oct 8 13:27:39 EDT 2013; so still should be plenty old for most distributions. Even RedHat 6 supports cmake 2.8.12 ... https://access.redhat.com/errata/RHBA-2014:1506.html Signed-off-by: Robin Getz <rgetz@mathworks.com>
