The current default timeouts that are used for the tests run by ctest are currently 1500 seconds per test. This is adequate for most situations, but for the quaduple precision case that is implemented by software rather than hardware, the tests can run slower than ordinary by two orders of magnitude, i.e., a few of the tests require ~1800 seconds to complete
on my fairly fast Intel PC. Thus, I recommend you change that default timeout from 1500 to 15000. (This simple change was agreed to in the general lapack forum discussion in 2011, but it must have gotten lost so I am bringing up this topic again in the feature request part of the forum in hope that some action will be taken.)
