C++ requirement

[gaul]

Which version of C++ does thermald require? I see calls to std::move, std::to_string, and foreach loops which suggests C++11. Can we specify the specific version in AM_CXXFLAGS?

6defd99 suggests that thermald intends to use C++0x and support GCC 5.x. Is the intent to support some older distro like RHEL? Specifically it would be nice to require C++17 since this introduced std::string_view.

This does support some older RHEL or may be others. So not sure if we can use new methods without breaking older distros.

Which RHEL should thermald support?

• RHEL 7 supports C++11 (already EOL)
• RHEL 8 supports C++17
