# This file is the CEF CMake configuration entry point and should be loaded
# using `find_package(CEF REQUIRED)`. See the top-level CMakeLists.txt file
# included with the CEF binary distribution for usage information.
#

# in order for CEF to be found and usable on macOS, you should
# - download a full (not minimal) binary release of CEF from https://cef-builds.spotifycdn.com/
# - unpack the download, create a symlink to $EXTERNLIBS/cef
# - go to $EXTERNLIBS/cef/Release
# - build libcef_dll_wrapper: execute `cmake .`, followed by make/ninja
# - use ad-hoc code signing: `codesign -s - "Chromium Embedded Framework.framework"`
# - create symlinks to $EXTERNLIBS/ALL: go to $EXTERNLIBS, `stow -t ALL -d cef Release`

# - Find CEF
# Find the CEF includes and library
#
#  CEF_INCLUDE_DIR - Where to find CEF includes
#  CEF_LIBRARIES   - List of libraries when using CEF
#  CEF_FOUND       - True if CEF was found
