# Findwfassoc.cmake
# ----------------
# Find wfassoc library and headers.
#
# This module requires the user to set wfassoc_ROOT to the installation
# directory of wfassoc. The directory structure under wfassoc_ROOT must be:
#   bin/     - contains wfassoc_cdylib.dll
#   include/ - contains wfassoc.h and wfassoc.hpp
#   lib/     - contains wfassoc_cdylib.dll.lib (import library)
#
# This module defines the following variables:
#   wfassoc_FOUND          - True if wfassoc was found
#   wfassoc_INCLUDE_DIRS   - Path to wfassoc include directory
#   wfassoc_LIBRARIES      - Path to wfassoc import library
#   wfassoc_DLL            - Path to wfassoc DLL
#   wfassoc_ROOT           - The root directory (user-provided)
#
# This module also creates the following imported targets:
#   wfassoc::wfassoc       - Main wfassoc library (includes both include and link)
