# This module try to find the Guideline Support Library (GSL) provided by Microsoft.
# Once done this will define

# MSGSL_FOUND - Microsoft GSL found
# MSGSL_INCLUDE_DIR - Microsoft GSL include directory
#
# Available targets:
# MSGSL::MSGSL
#
# This will define the following cache variables:
# MSGSL_CONTRACT_VIOLATION_CONFIG = Throw/Terminate/Unenforced
