Note this can be useful if for some reason the "host" requirement changes, like when it is overridden from downstream, or if it defined
a version range and resolved to another version.

Additionally, the syntax ``<host_version:mylib>`` can be used to specify the name of the package to be tracked,
should the *requires* and *tool_requires* have different names. For instance:

.. code-block:: python

from conan import ConanFile
class mylibRecipe(ConanFile):
name = "mylib"
version = "0.1"
def requirements(self):
self.requires("gettext/2.31")
def build_requirements(self):
self.tool_requires("libgettext/<host_version:gettext>")
