Windows build hardcodes "C:\tools\fluidsynth\bin" causing FileNotFoundError

[zhangpanyang]

Version: 1.3.4
OS: Windows 11

Problem

When importing fluidsynth on Windows with Python 3.8:

import fluidsynth

It raises

FileNotFoundError: [WinError 3] The system cannot find the specified path: 'C:\\tools\\fluidsynth\\bin'

This is caused by the lines in fluidsynth.py:

# DLL search method changed in Python 3.8
# https://docs.python.org/3/library/os.html#os.add_dll_directory
if hasattr(os, 'add_dll_directory'):  # Python 3.8+ on Windows only
    os.add_dll_directory(os.getcwd())
    os.add_dll_directory('C:\\tools\\fluidsynth\\bin')
    # Workaround bug in find_library, it doesn't recognize add_dll_directory
    os.environ['PATH'] += ';C:\\tools\\fluidsynth\\bin'

This will fail if C:\\tools\\fluidsynth\\bin does not exist on the user's machine.

@zhangpanyang Is this problem still happening when using pyfluidsynth v1.4.0?
