[CMake] increase output threshhold

[Andreas Pakulat]

Hi,

I'm looking for a way to increase (or even unlimit) the output threshold
that cmake uses for the stdout/stderr output of a unit-test. I'm having a
problem with one of my tests which hangs, only when running the whole suite
and unfortunately this one produces tons of output (which I can't disable).
