CMake file for compiling with Intel SGX.
To make compiling code using SGX with CMake easier, a single FindSGX.cmake file is provided for the purpose.
This code example is from official Intel SGX sample Cxx11SGXDemo.
Please refer to the CMakeLists.txt file for how to use FindSGX.cmake file.
list(APPEND CMAKE_MODULE_PATH ${PATH_TO_FindSGX.cmake_FILE})
find_package(SGX REQUIRED)
