# FindCrashpad
# ------------
# Locate Crashpad sources and build
#
# The ``CRASHPAD_BUILD_DIR``, ``CRASHPAD_SOURCE_DIR``, and ``CRASHPAD_OBJECT_DIR``
# (APPLE-only) variables can be used as additional hints.
#
# If you built crashpad with the default setup in "out/Default" within the
# source directory, you can set the ``Crashpad_ROOT`` variable to the source
# directory, or add it to ``CMAKE_PREFIX_PATH``.
#
# If found, this will define the following variables:
#
# ``Crashpad_FOUND``
#     True if the necessary Crashpad files have been found
#
# ``Crashpad::Crashpad``
#     Imported target to build against
#
# ``CRASHPAD_BIN_DIR``
#     Directory where the crashpad_handler executable is found
