-------
Finds the libffi library.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following imported targets, if found:
``libffi``
The ffi library
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``libffi_FOUND``
True if the system has the Ffi library.
#]=======================================================================]
# Use pkg-config if available
find_package(PkgConfig QUIET)
pkg_check_modules(PC_LIBFFI QUIET libffi)
# Find the headers and library
find_path(
libffi_INCLUDE_DIR
NAMES "ffi.h"
HINTS "${PC_LIBFFI_INCLUDE_DIR}")
find_library(
libffi_LIBRARY
NAMES "ffi" "libffi"
HINTS "${PC_FFI_LIBDIR}")
# Extract additional flags if pkg-config is available
if(PC_FFI_FOUND)

endif()
# Forward the result to CMake
