opencascade: relocatable shared libs on macOS + bump requirements + modernize

[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!

this will trigger https://github.com/conan-io/conan-center-index/blob/master/docs/error_knowledge_base.md#kb-h019-cmake-file-not-in-build-folders right ?

[SpaceIm]

No. I guess because cmake file is in build_modules. And it's good, you don't want to add this folder to builddirs (because buildirsare prepended to CMAKE_MODULE_PATH in cmake generator, and we don't want consumer to be able to include this cmake file, it's an internal detail of cmake_find_package and cmake_find_package_multi generator).

Well, take a look at the last lines in https://c3i.jfrog.io/c3i/misc/logs/pr/8869/1-configs/windows-visual_studio/opencascade/7.5.0//4eb25c38fccb68e6473f428d27ae7648cf3422c9-build.txt

ok, so it' just a warning now, but this hook is wrong, you don't have to put cmake files listed in build_modules, in builddirs as well.

From hook description:

It is only allowed to put build files in builddirs because the generators might be able to include them when needed, but only if they are located in well known paths.

No, generators use absolute path of the cmake file thanks to build_modules values, they don't need builddirs to append something in CMAKE_MODULE_PATH. builddirs is needed if you want to append something to CMAKE_MODULE_PATH in cmake or CMakeToolchain generators, that's all. Basically builddirs is for cmake module files which are packaged and may be included directly by consumers in their CMakeLists.

I think we first have to make this discussion in https://github.com/conan-io/hooks/, and fix the hooks, before spreading this all over CCI

This recipe is so hard to build in CI of CCI.
