# libaec-config.cmake
# -------------------
#
# Finds the AEC library.
#
# Static vs. shared
# -----------------
# To make use of the static library instead of the shared one, one
# needs to set the variable libaec_USE_STATIC_LIBS to ON before
# calling find_package.
# Example:
#   set(libaec_USE_STATIC_LIBS ON)
#   find_package(libaec CONFIG)
#
# This will define the following variables:
#
#   libaec_FOUND     - True if the system has the AEC library.
#   libaec_VERSION   - The version of the AEC library which was found.
#   SZIP_FOUND       - True if the system has the SZIP library.
#   SZIP_VERSION     - The version of the SZIP library which was found.
#   SZIP_LIBRARIES   - All the required libraries to make use of SZIP.
#   SZIP_INCLUDE_DIR - SZIP include directory.
#
# and the following imported targets:
#
#   libaec::aec-shared  - The shared AEC library target (if it was built).
#   libaec::sz-shared   - The shared SZIP compatible version of the AEC library
#                         (if it was built).
#   libaec::aec-static  - The static AEC library target (if it was built).
#   libaec::sz-static   - The static SZIP compatible version of the AEC library
#                         (if it was built).
#   libaec::aec         - The (shared or static) AEC library target (according
#                         to the value of libaec_USE_STATIC_LIBS).
#   libaec::sz          - The (shared or static) SZIP compatible version of the
#                         AEC library (according to the value of
#                         libaec_USE_STATIC_LIBS).
