# - Find DbgHelp
# Find the DbgHelp library
# This module defines
#  DBGHELP_INCLUDE_DIR, where to find dbghelp.h, etc.
#  DBGHELP_LIBRARIES, the libraries needed to use DbgHelp.
#  DBGHELP_FOUND, If false, do not try to use DbgHelp.

# MSVC knows how to find the Windows SDK on its own, and replicating that
# in CMake is very tricky, especially with the SDK's layout changing
# occasionally. So instead we'll just leave it to MSVC to do correctly.
