cmake package does not install a cmake3 executable/link to cmake

[Thibaulltt]

Solution to issue cannot be found in the documentation.

• I checked the documentation.

Issue

On most Linux distros, newer versions of CMake have two ways of being invoked: through cmake and cmake3 (symbolic link to cmake). This CMake recipe does not provide this link, and thus tools like scikit-build-core find the system CMake instead of the one provided by conda (because of this line).

Note: I use Micromamba in the scripts below, but the same happens on Anaconda.
