For some of the test applications I get a boost linker error:

[ 19%] Linking CXX executable TestFFT
../../src/libippl.a(Timer.cpp.o): In function `Timer::Timer()':

collect2: error: ld returned 1 exit status
make[2]: *** [ippl/test/FFT/TestFFT] Error 1
make[1]: *** [ippl/test/FFT/CMakeFiles/TestFFT.dir/all] Error 2

This was with the recommended module list:

Currently Loaded Modulefiles:
  1) cmake/3.10.3            4) boost/1.68.0            7) gsl/2.5                10) opal-toolchain/master
  2) gcc/7.3.0               5) hdf5/1.10.4             8) trilinos/12.12.1
  3) openmpi/3.1.3           6) H5hut/2.0.0rc5          9) OpenBLAS/0.2.20

This can be fixed by linking to the boost_timer library.
