mingw: split windows and linux recipes

[ericLemanissier]

Specify library name and version: mingw-w64/*

there is no change at all in the recipe, just a separation of the 2 paths (linux and windows), which are 99% of the time different.

• I've read the guidelines for contributing.
• I've followed the PEP8 style guides for Python code in the recipes.
• I've used the latest Conan client version.
• I've tried at least one configuration locally with the
  conan-center hook activated.

Context: this recipe is more or less "dead" because there is no plan to put newer version on http://sourceforge.net/projects/mingw-w64/. I will make a new windows recipe based on https://github.com/niXman/mingw-builds when a new tag will be made (niXman/mingw-builds#575)

this is kinda unfortunate. are these niXman binaries considered official? are they drop-in replacements for mingw-w64?

[ericLemanissier]

AFAIK, there are no "official" migw-w64 binaries. But NiXman was already one of the contributors behind the mingw-builds binaries this recipe downloads from sourceforge

at this point, I am not completely sure if it should be just mingw or nixman-mingw to distinguish distribution.
if it's the main source of truth, it's okay to name it just mingw to avoid unnecessary confusion for consumers.
but there are other distributions, like https://nuwen.net/mingw.html or one provided with MSYS. are they considered equal?

[ericLemanissier]

Just to confirm what I said above, there is a file named build-info.txt in existing mingw-w64\8.1\_\_\package\*** and the file says user : nixman.
You are right that the situation needs to be improved regarding the multiple versions of mingw. I don't know if one is better than the other, but there are (at least) all the following:

• all the ones on https://www.mingw-w64.org/downloads/ (including mingw-builds)
• https://nuwen.net/mingw.html
• https://winlibs.com/
• https://osdn.net/projects/mingw/ which is rising from the ashes of https://mingw.osdn.io/ (mingw.org, which is now down)

EDIT: see #8349 The old sourceforge artifacts are consumable exactly the same way as new github artifacts, so the recipe is the same for both. When #8349 we should deprecate mingw-w64/8.1 and recommend migrating to mingw-builds/*

All green in build 2 (7664bf05c30d4663b1f405b92f8d248c8fa8ad41):

closing this one in favor of #8349
