Merge pull request #1438 from delcypher/cmake_old_glibc_librt 
[CMake] Fix #1437
 2018-01-03 08:41:15 -08:00
Dan Liew
e9be339d9d [CMake] Fix #1437. 
The `clock_gettime()` function in glibc < 2.17 required linking against
librt. Until #1437 nobody had tried using the CMake build system with
a really old version of glibc (in this case 2.12).

The python build system always linked against librt but the CMake build
system never tried to link against it leading to link failures.

This patch teaches the CMake build system to detect if librt is required
when linking against `clock_gettime()` and adds `rt` as a link
dependency if necessary.
