We must not provide the /Externals directory as global include directory.
Here, this yield a crash because of external minizip header and system library mismatch.
Soundtouch itself recormends to include it with <SoundTouch.h> and -I/usr/include/soundtouch, so this should fit better.
Previously the logging was a in a little bit of a disarray. Some things
were in namespaces, and other things were not.
Given this code will feature a bit of restructuring during the
transition over to fmt, this is a good time to unify it under a single
namespace and also remove functions and types from the global namespace.
Now, all functions and types are under the Common::Log namespace. The
only outliers being, of course, the preprocessor macros.
Constructs the strings directly within the container instead of
performing a construction, then a copy.
The reasoning is that the BACKEND_* strings are const char arrays, so
the push_back code is equivalent to:
push_back(std::string(BACKEND_WHATEVER)) instead of forwarding the
arguments to a constructed instance directly in the container.
