# FindITT
# ---------
#
# Find Instrumentation and Tracing Technology (ITT) API include dirs and libraries
#
# Use this module by invoking find_package with the form
#
# ::
#
# find_package(ITT
# [REQUIRED] # Fail with error if ITT is not found
# )
#
# This module finds headers and libraries
# For the former case results are reported in variables
#
# ::
#
# ITT_FOUND - True if headers and requested libraries were found
# ITT_INCLUDE_DIRS - ITT include directories
# ITT_LIBRARIES - ITT libraries to be linked
#
# This module reads hints about search locations from variables
#
# ::
#
# SEAPI_ROOT - Preferred installation path for Intel® Single Event API (Intel® SEAPI)
# (https://github.com/intel/IntelSEAPI)
# ITT_ROOT/
# CMAKE_ITT_HOME - Preferred installation path for standalone ITT library
# INTEL_LIBITTNOTIFY32/
# INTEL_LIBITTNOTIFY64 - Preferred ITT library directory
# VTUNE_AMPLIFIER_<YEAR>_DIR - VTune Amplifier XE installation path which is set by amplxe-vars.sh/bat script
# See notes about [ITT_NO_VTUNE_PATH] below
# CMAKE_VTUNE_HOME - Explicitly defined VTune Amplifier XE installation path
#
# Other variables one may set to control this module are
#
# ::
#
# ITT_DEBUG - Set to ON to enable debug output from FindITT.
# Please enable this before filing any bug report.
# ITT_NO_VTUNE_PATH - Set to ON to not try to find VTUNE_AMPLIFIER_<YEAR>_DIR environment variable
#
# Example to find ITT headers and libraries
#
# ::
#
# find_package(ITT)
# if (ITT_FOUND)
# include_directories(${ITT_INCLUDE_DIRS})
# add_executable(foo foo.cc)
# target_link_libraries(foo ${ITT_LIBRARIES})

# Example to find ITT library and use imported targets::

# find_package(ITT REQUIRED)
