[glfw] ImportError: Failed to load GLFW3 shared library

After compiling and starting the excecutable via CMD, we get:

Traceback (most recent call last):
  File "C:\Users\ADMINI~1\PYCHAR~1\NUITKA~1\APP~1.DIS\app.py", line 6, in <module>

ImportError: Failed to load GLFW3 shared library.

(The missing DLL is located in venv\glfw\glfw3.dll) If we manually copy it over and attempt to run again we get:

TypeError: 'NoneType' object is not callable

During handling of the above exception, another exception occurred:

Code snippet to reproduce:

import time

import concur as c

executor = ThreadPoolExecutor()


def timer():
	yield from c.orr([c.text(""), c.button("Start timer")])
	yield
	future = executor.submit(lambda: time.sleep(3))
	yield from c.orr([c.text("waiting for 3s..."), c.button("Cancel"), c.Block(future)])


def app():
	return c.orr([c.forever(timer) for _ in range(3)])

Installed via python -m pip install nuitka

Important note If we try to run this code on a machine which cannot render opengl and the above error would be fixed, we would get GLFWError: (65542) b'WGL: The driver does not appear to support OpenGL' warnings.warn(message, GLFWError) which is then considered ‘normal’. To efficiently test it we need to run the compiled code on a machine which can render opengl (any > i5 processor or a proper GPU will suffice).

Part of the current pre-release, I expect to make a release relatively soon.
