# Locate an BOLT implementation.
#
# Defines the following variables:
#
# BOLT_FOUND - Found an Bolt imlementation
#
# Also defines the library variables below as normal
# variables.
#
# BOLT_LIBRARIES - These contain debug/optimized keywords when a debugging library is found
# BOLT_INCLUDE_DIRS - All relevant Bolt include directories
#
# Accepts the following variables as input:
#
# BOLT_ROOT - (as a CMake or environment variable)
# The root directory of an BOLT installation
#
# FIND_LIBRARY_USE_LIB64_PATHS - Global property that controls whether FindBOLT should search for
# 64bit or 32bit libs
#
#-----------------------
# Example Usage:
#
# find_package(BOLT REQUIRED)
# include_directories(${BOLT_INCLUDE_DIRS})
#
# add_executable(foo foo.cc)
# target_link_libraries(foo ${BOLT_LIBRARIES})
#
