fix macOS build (following Projucer changes made in Windows, which removed /Applications/JUCE/modules from its headers). move JUCE headers under source control, so that Windows and macOS can both build against same version of JUCE. remove AUv3 target (I think it's an iOS thing, so it will never work with this macOS fluidsynth dylib).

/**
|
||||
A simple class for holding temporary references to a string literal or String.
|
||||
|
||||
Unlike a real String object, the StringRef does not allocate any memory or
|
||||
take ownership of the strings you give to it - it simply holds a reference to
|
||||
a string that has been allocated elsewhere.
|
||||
The main purpose of the class is to be used instead of a const String& as the type
|
||||
of function arguments where the caller may pass either a string literal or a String
|
||||
object. This means that when the called uses a string literal, there's no need
|
||||
for an temporary String object to be allocated, and this cuts down overheads
|
||||
substantially.
|
||||
|
||||
Because the class is simply a wrapper around a pointer, you should always pass
|
||||
it by value, not by reference.
|
||||
|
||||
@code
|
||||
void myStringFunction1 (const String&);
|
||||
void myStringFunction2 (StringRef);
|
||||
|
||||
myStringFunction1 ("abc"); // Implicitly allocates a temporary String object.
|
||||
myStringFunction2 ("abc"); // Much faster, as no local allocations are needed.
|
||||
@endcode
|
||||
|
||||
For examples of it in use, see the XmlElement or StringArray classes.
|
||||
|
||||
Bear in mind that there are still many cases where it's better to use an argument
|
||||
which is a const String&. For example if the function stores the string or needs
|
||||
to internally create a String from the argument, then it's better for the original
|
||||
argument to already be a String.
