Since C++17, the introduction of deduction guides for locking facilities
means that we no longer need to hardcode the mutex type into the locks
themselves, making it easier to switch mutex types, should it ever be
necessary in the future.
Reduces the potential amount of rebuilding necessary if any headers
change. In particular, we were including a header from the core library
when we don't even link the core library to the web_service library, so
this also gets rid of an indirect dependency.
This is more localized to what we want to enforce directory-wise with
the project. CMAKE_SOURCE_DIR indicates the root of the source tree, but
this would cause the wrong behavior if someone included yuzu as part of
a larger buildsystem (for whatever reason). Instead, we want to use the
directory where the "project(yuzu)" command was declared as the root
path reference.
Given we link in httplib privately, we can also make the definition
enabling OpenSSL support private as well. Prevents leaking a definition
into other libraries that link with this one, like the core library.
Like with TelemetryJson, we can make the implementation details private
and avoid the need to expose httplib to external libraries that need to
use the Client class.
Users of the web_service library shouldn't need to care about an
external library like json.h. However, given it's exposed in our
interface, this requires that other libraries publicly link in the JSON
library. We can do better.
By using the PImpl idiom, we can hide this dependency in the cpp file
and remove the need to link that library in altogether.
Taking them by const reference isn't advisable here, because it means
the std::move calls were doing nothing and we were always copying the
std::string instances.
* WebService: Verify username and token; Log errors in PostJson
* Fixup: added docstrings to the functions
* Webservice: Added Icons to the verification, imrpved error detection in cpr, fixup nits
* fixup: fmt warning
