FESAPI
--------

Find the native FESAPI includes and library.
Heavily inspired by the official FindZLIB cmake module v3.27.

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

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

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

This module defines the following variables:

::

  FESAPI_INCLUDE_DIRS   - where to find zip.h, unzip.h, etc.
  FESAPI_LIBRARIES      - List of libraries when using fesapi.
  FESAPI_FOUND          - True if fesapi found.

Hints
^^^^^

A user may set ``FESAPI_ROOT`` to a fesapi installation root to tell this
module where to look.
