Subject: changed default behaviour for clock_gettime()
X-Git-Url: http://git.code-monkey.de/?a=commitdiff_plain;h=4104c875c929e8c071b4436003c43d81f9e8e896;hp=a0f585591388e8245bd14f4d37ef7b667f036672;p=umurmur.git

changed default behaviour for clock_gettime()

CMake now checks first for clock_gettime() in librt, so
we can make use of its capabilities when available.
