CMake-Integrated SGX Build Framework

To support the separation of Enclave and App architectures, this framework builds a CMake-compatible compilation system, optimizing modular development, dependency management, and cross-component integration, significantly reducing the complexity of SGX project builds.The following is an example of using this framework.

• Project CmakeList

cmake_minimum_required(VERSION 3.19)
project(http_test "C" "CXX")

set(PROJECT_VERSION 0.0.1)

find_package(ssgx REQUIRED)

add_subdirectory(Enclave)
add_subdirectory(App)

• App CmakeList

set(app "${PROJECT_NAME}_app")

ssgx_add_untrusted_executable(${app}
        SRCS 
            host.cpp
        EDL 
            Enclave.edl
        EDL_SEARCH_PATHS 
            ../ 
            ${ssgx_EDL_DIRS}
        UNTRUSTED_LIBS
            ssgx::ssgx_http_u
            ssgx::ssgx_log_u
            ssgx::ssgx_config_u
            ssgx::ssgx_utils_u
            ssgx::ssgx_filesystem_u
)

target_compile_features(${app} PRIVATE cxx_std_11)

• Enclave CmakeList

set(enclave "${PROJECT_NAME}_enclave")
ssgx_add_enclave_library(${enclave}
        USE_SGXSSL OFF
        SRCS 
            Enclave.cpp
        TRUSTED_LIBS
            ssgx::ssgx_utils_t
            ssgx::ssgx_config_t
            ssgx::ssgx_decimal_t
            ssgx::ssgx_log_t
            ssgx::ssgx_json_t
            ssgx::ssgx_http_t
            ssgx::ssgx_filesystem_t
        EDL Enclave.edl
        EDL_SEARCH_PATHS 
            ../ 
            ${ssgx_EDL_DIRS}
)

target_compile_features(${enclave} PRIVATE cxx_std_17)

ssgx_enclave_sign(${enclave}
        KEY Enclave_private_test.pem
        CONFIG Enclave.config.xml
)

important

To use this feature, cmake version must be at least 3.19.
