Updated the readme to build Allen from the nightlies.
- The latest Gaudi was not happy with CMake 3.14:
CMake Error at /cvmfs/lhcbdev.cern.ch/nightlies/lhcb-head/latest/Gaudi_master/InstallArea/x86_64-centos7-gcc9-opt/lib/cmake/Gaudi/GaudiConfig.cmake:73 (cmake_policy): An attempt was made to set the policy version of CMake to "3.15" which is greater than this version of CMake. This is not allowed because the greater version may have new policies not known to this CMake. You may need a newer CMake version to build this project.
(later a misleading error that
jemalloc is not found is printed)
- Allen (and Moore) complained about missing Intel tools:
-- Could NOT find IntelAmplifier (missing: INTELAMPLIFIER_INCLUDE_DIRS INTELAMPLIFIER_LIBITTNOTIFY INTELAMPLIFIER_LIB_DIRS INTELAMPLIFIER_AMPLXE_CL_EXECUTABLE) ... -- Missing Gaudi's required dependencies: * IntelAmplifier
