cfgfile: add Conan v2 support, add version 0.2.11

[igormironchik]

Specify library name and version: cfgfile/0.2.11

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'm the author of this library.

• I've read the contributing guidelines.
• 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.

It seems to be almost complete.
There are several minor issues, could you please fix them?

Suggested change

	tc.cache_variables["BUILD_EXAMPLES"] = False
	tc.cache_variables["BUILD_TESTS"] = False
	if Version(self.version) >= "0.2.9":
	tc.cache_variables["USE_INTERNAL_ARGS_PARSER"] = False
	tc.variables["BUILD_EXAMPLES"] = False
	tc.variables["BUILD_TESTS"] = False
	if Version(self.version) >= "0.2.9":
	tc.variables["USE_INTERNAL_ARGS_PARSER"] = False

Please use variables if possible.

It's not possible in case of cfgfile. In my CMakeLists.txt options are set before project(), that is why I use cache_variables.

cmake_minimum_required( VERSION 3.19 )

set( CFGFILE_VERSION "0.2.11" )

option( BUILD_EXAMPLES "Build examples? Default ON." ON )
option( BUILD_TESTS "Build tests? Default ON." ON )

if( NOT CMAKE_BUILD_TYPE )
	set( CMAKE_BUILD_TYPE "Release"
		CACHE STRING "Choose the type of build."
		FORCE)
endif( NOT CMAKE_BUILD_TYPE )

SET( CMAKE_CXX_STANDARD 14 )

SET( CMAKE_CXX_STANDARD_REQUIRED ON )

project( cfgfile )

[igormironchik]

But with USE_INTERNAL_ARGS_PARSER I can use variables...
