Unable to determine tool version if tool definition for newer version doesn't exist

[micahsnyder]

Mussels tool definitions must exist to be able to identify a version of the tool. If the tool installed is newer than the definitions available and a >= is used for the tool to specify the minimum tool version Mussels thinks the tool is missing.

Specifically what I'm observing is my PC has CMake 3.18, but I only have tool definitions for cmake 3.13 - 3.15. If my recipe says it needs cmake, then it's fine, but if it says cmake>= 3.14, then it thinks CMake is missing.

Ideally there would be a tool command that could be defined for a generic version-less tool definition that could identify the tool version programmatically so a version-specific definition wouldn't be required.

Food for thought.
