Does not build on Ubuntu Focal Fossa about frequent-cron

[Kramerican]

Without knowing what the hell I'm doing, I figured I'd try the suggestion from here:

facebookarchive/Surround360#3

And added SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread") to CMakeLists.txt so it becomes:

cmake_minimum_required(VERSION "2.8.0")
set(MAIN_EXECUTABLE frequent-cron)
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")

project(${MAIN_EXECUTABLE} CXX C)
add_subdirectory(src)

Seems to totally work. But I'd love to get confirmation that it is OK/correct to do this :D

Thanks for this @Kramerican !

Yeah, I think I'll remove the boost dependency. It's a bit of an overkill to require it for this and it causes headaches with newer versions.

Any thoughts on the oldest linux versions that we should support? I was thinking support for Ubuntu 14 and newer is probablly fine.

My two cents would be that Ubuntu 14+ is plenty conservative enough :)
