Missing define 'BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG' in CMake configuration

[fventuri-availity]

Please note that the version of Impala that comes with Cloudera CDH 5.11 (and possibly with previous versions of CDH) was compiled using the define 'BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG' (see here - http://www.boost.org/doc/libs/1_64_0/doc/html/date_time/details.html#date_time.buildinfo). This define causes the boost 'time_duration' type to use nanoseconds and be 96 bits long (the default is 64 bit).
If a C++ Impala UDF uses boost time/date functions (for instance to deal with Impala timestamps) and is compiled without this define, the results will likely be incorrect and it might cause the Impala daemon to crash.
A simple way to define the compile preprocessor flag 'BOOST_DATE_TIME_POSIX_TIME_STD_CONFIG' is by adding the following line to 'CMakeLists.txt':

add_definitions(-DBOOST_DATE_TIME_POSIX_TIME_STD_CONFIG)
