abseil: cross-compatibility conan v1/v2

[SpaceIm]

Specify library name and version: lib/1.0

This is also a good place to share with all of us why you are submitting this PR (specially if it is a new addition to ConanCenter): is it a dependency of other libraries you want to package? Are you the author of the library? Thanks!

• 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.

ERROR: abseil/20200923.3 (test package): Error in build() method, line 12
	cmake.definitions["CXX20_SUPPORTED"] = tools.Version(self.deps_cpp_info["abseil"].version) > "20210324.2"
	ConanException: Invalid version 'None'

Why is it not valid in test_v1_package? I've kept the same conanfile 😲 , and I see recent PR of abseil where this previous test_package is working fine.

We have just upgraded to Conan 1.50.1 this afternoon. Maybe a regression?

I guess, I can reproduce this issue locally with conan create . abseil/20211102.0@ -tf test_v1_package. Maybe a breaking change where self.deps_cpp_info values are unkown in build() but not in generate()?

Fixed in conan 1.51.1 by conan-io/conan#11790. So waiting an update of conan version in CCI.

All green in build 6 (8b73adcb3951f165bd51702796b65e386e0db456):
