Unable to compiler on debian for gnu g++ compiler

[starkdg]

When following the compiler insructions, the following error. The timer library is installed.

This is on a debian system with gnu c compiler.

I fixed this by replacing by adding chrono in the find_package command in CMakeLists.txt file:

find_package(Boost REQUIRED COMPONENTS system fileystem iostreams timer date_time chrono)
