#
# - Find EZTRACE include dirs and libraries
# Use this module by invoking find_package with the form:
# find_package(EZTRACE
# [REQUIRED]) # Fail with error if eztrace is not found
#
# EZTRACE depends on the following libraries:
# - libbfd.so
# - libiberty.so (optional)
#
# This module finds headers and eztrace library.
# Results are reported in variables:
# EZTRACE_FOUND - True if headers and requested libraries were found
# EZTRACE_INCLUDE_DIRS - eztrace include directories
# EZTRACE_LIBRARY_DIRS - Link directories for eztrace libraries
# EZTRACE_LIBRARIES - eztrace component libraries to be linked
#
# The user can give specific paths where to find the libraries adding cmake
# options at configure (ex: cmake path/to/project -DEZTRACE_DIR=path/to/eztrace):
# EZTRACE_DIR - Where to find the base directory of eztrace
# EZTRACE_INCDIR - Where to find the header files
# EZTRACE_LIBDIR - Where to find the library files
# The module can also look for the following environment variables if paths
# are not given as cmake variable: EZTRACE_DIR, EZTRACE_INCDIR, EZTRACE_LIBDIR
