Toward nicer behaviour for selecting static/shared libraries, respecting the Meson convention (default_library=) rather than using a custom option - some nasty bits still to be tested on Windows

# In the MSVC world we have a quandary, partly as a result of

# wanting to use naming compatible with our previous/other build

# systems.
|

#
|

# Meson would like to use rubberband.dll for the dynamic library,
|
||||
# rubberband.lib for the import library, and librubberband.a for the
|
||||
# static library. This is kind of ok, even though lib*.a is not a
|
||||
# very familiar naming style here - except that previously we called
|
||||
# the static library rubberband-static.lib. (It would be usual to
|
||||
# expect some .lib file to be produced as a static library,
|
||||
# especially if default_library=static is set.)
|
||||
#
|

# Our "solution" is to leave alone if default_library=shared (when
|
||||
# the Meson and MSVC ways are the same), but emit an additional

# static .lib otherwise, called either rubberband-static.lib if
