Find the MSSQL Native Client includes and library.

IMPORTED Targets
^^^^^^^^^^^^^^^^

This module defines :prop_tgt:`IMPORTED` target ``MSSQL_NCLI::MSSQL_NCLI``, if
MSSQL_NCLI has been found.

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

::

  MSSQL_NCLI_INCLUDE_DIRS   - where to find sqlncli.h, etc.
  MSSQL_NCLI_LIBRARIES      - List of libraries when using MSSQL_NCLI.
  MSSQL_NCLI_FOUND          - True if MSSQL_NCLI found.
  MSSQL_NCLI_VERSION        - Major Version (11, 10, ...). Can be a input variable too
