Improves move application and validation

Refactors move application to handle cases where a move cannot be applied due to manifold configuration.

Skips the test when a move cannot be applied, and logs a warning message providing better test reporting.

Also, the Boost library is now found using config mode. A cmake policy is set to avoid warnings.
