Specify library name and version: pcre/8.45

I'm getting a conflict in one of my recipes. Weirdly it occurs on mac and msvc, but not on gcc.

    'pcre/8.45' requires 'zlib/1.2.11' while 'minizip/1.2.12' requires 'zlib/1.2.12'.

My conanfile.py has self.requires("zlib/1.2.12"). My test_package/conanfile.py has self.requires("minizip/1.2.12") (and I tried adding self.requires("zlib/1.2.12") in the test_package/conanfile.py too)

• 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.
