8# Config defining how CMake should find ExecuTorch package. CMake will search
9# for this file and find ExecuTorch package if it is installed. Typical usage
10# is:
11#
12# find_package(executorch REQUIRED)
13# -------
14#
15# Finds the ExecuTorch library
16#
17# This will define the following variables:
18#
19#   EXECUTORCH_FOUND        -- True if the system has the ExecuTorch library
20#   EXECUTORCH_INCLUDE_DIRS -- The include directories for ExecuTorch
21#   EXECUTORCH_LIBRARIES    -- Libraries to link against
22#
23# The actual values for these variables will be different from what executorch-config.cmake
24# in executorch pip package gives, but we wanted to keep the contract of exposing these
25# CMake variables.
