GMP Conan 2.0 compatibilty

[System-Arch]

Specify library name and version: gmp/6.2.1

This pull requests builds upon @SpaceIm's work in PR #14103 and is my effort to help move it forward. I have gmp building with Conan 2.0 on Linux and Windows in my own build environment. Hopefully the fixes will apply with v1 in CCI as well.

• I've read the contributing guidelines.
• I've used a recent Conan client version close to the currently deployed.
• I've tried at least one configuration locally with the conan-center hook activated.

@System-Arch I think recipe is correct. I see regressions in your PR. What do you want to fix?

Hi @SpaceIm,
Thanks for your message. It was certainly not my intent to introduce any regressions. Please let me know what you are seeing.
The goal of my PR was to get the recipe to work with Conan 2.0. I observed two issues:

1. Conan 2.0 doesn't support self.deps_user_info (see [question] What is the disposition of deps_user_info and user_info_build in Conan 2.0 conan#12812)
2. The test_package test does not pass with Conan 2.0 due to use of self.options["gmp"]

The PR attempts to address both of these issues. Thanks

Conan 2.0 doesn't support self.deps_user_info (see [question] What is the disposition of deps_user_info and user_info_build in Conan 2.0 conan#12812)

Ok, automake recipe has been updated and it's now possible to query custom conf for msvc wrappers

The test_package test does not pass with Conan 2.0 due to use of self.options["gmp"]

For this one there is a nice trick proposed by @jcar87 based on ctest. It requires to add extra stuff in CMakeLists of test package (enable_testing(), add_test() for each executable). Then you don't need to test recipes options anymore in test(), just run ctest once with few appropriate flags. See test package of boost recipe.

It was certainly not my intent to introduce any regressions. Please let me know what you are seeing.

At least removal of extra double quotes around lib -nologo, from my experience this one must be protected. And removal of str() while testing Visual Studio/msvc, this part is intentional to support conan v1 & v2.

For this reason you might find that not all the references have been launched or not all the configurations for a given reference. Also, take into account that we cannot guarantee the order of execution as it depends on CI workload and workers availability.}
