Unhandled python exception windows 10 vcpkg cgal

[blobfish]

Describe the bug Running meson setup with a CGAL Dependency results in unhandled exception.

To Reproduce vcpkg install cgal:x64-windows

meson.build:

project('test_project', 'cpp',
  version : '0.1.0',
  license : 'GPL-3+',
  meson_version : '>=0.52.0',
  default_options : ['warning_level=3', 'cpp_std=c++17']
)

cgal = dependency('CGAL', version : '>=4.13', include_type : 'system')

test_exe = executable('test', ['main.cpp']
  , dependencies : [cgal])

meson run:
