[bug] '/' path separator is not handled correctly on Windows by Conan 1.30.0

[db4]

Environment Details (include every applicable attribute)

• Operating System+version: Windows 10
• Conan version: 1.30.0
• Python version: 3.8.6

Steps to reproduce

The following consumer recipe illustrates the problem:

from conans import ConanFile
import os

class TestConan(ConanFile):
    requires = "zlib/1.2.11@conan/stable"

    def imports(self):
        pkg = "zlib"
        path = "licenses/LICENSE"
        self.copy(path, dst=pkg, root_package=pkg)
        if not os.path.exists(os.path.join(pkg, path)):
            raise Exception("Import failure!")

It works with 1.29.2 but fails with 1.30.0. If I replace / with \\ it works with 1.30.0 as well.

I was just about to report that. In my case, the following does not work in my conan package:

    def imports(self):
        self.copy('some-folder/*', root_package='some-other-package')

The some-folder gets imported on mac and Linux, but not on Windows. Downgrade to conan v1.29.2 solved the issue.

Hi @db4, @DoDoENT,
Thanks a lot for reporting. I have been able to reproduce the issue, it was probably introduced by #7704
We'll fix as soon as possible.

Fixed by #7861, will be released in 1.30.2
