Hi dai

Of course, You can use any auto build system. If you want to use cmake, you need to add SGX related operations, to cmakelist file. For example, the operation to generate trust and untrust bridge code and operation to sign the enclave ...If you are familiar with cmake you can try that.  I'am not familiar with cmake, But it should be something like this.

#APP cmakelist

cmake_minimum_required(VERSION 3.5)

add_custom_command(OUTPUT Enclave_u.h Enclave_u.c
    COMMAND  $ENV{SGX_SDK}/bin/x64/sgx_edger8r --untrusted ../Enclave/Enclave.edl --search-path . --search-path /opt/sgxsdk/include
    COMMENT  "make ucode"  
)

add_custom_target(
    ucode ALL
    DEPENDS Enclave_u.h Enclave_u.c
)

aux_source_directory(. srcs)
add_executable(app ${srcs})

#Enclave cmakelist

cmake_minimum_required(VERSION 3.5)
message(STATUS "dealing with .edl")

include_directories(. $ENV{SGX_SDK}/include ../Include $ENV{SGX_SDK}/include/tlibc $ENV{SGX_SDK}/include/libcxx)
#execute_process(COMMAND  $ENV{SGX_SDK}/bin/x64/sgx_edger8r --trusted ./Enclave.edl --search-path . --search-path /opt/sgxsdk/include)
add_custom_command(OUTPUT Enclave_t.h Enclave_t.c
    COMMAND  $ENV{SGX_SDK}/bin/x64/sgx_edger8r --trusted ./Enclave.edl --search-path . --search-path /opt/sgxsdk/include
    COMMENT  "make tcode"  
)

add_custom_target(
    tcode ALL
    DEPENDS Enclave_t.h Enclave_t.c
)
add_custom_target()

aux_source_directory(. enclave_srcs)
aux_source_directory(./Edger8rSyntax edger_src)
aux_source_directory(./TrustedLibrary tlib_src)
message(STATUS, "$ENV{SGX_SDK}/lib64")

SET(CMAKE_EXE_LINKER_FLAGS "-Wl,--no-undefined -nostdlib -nodefaultlibs -nostartfiles -L/opt/sgxsdk/lib64 -Wl,-Bstatic -Wl,-Bsymbolic -Wl,--no-undefined -Wl,-pie,-eenclave_entry -Wl,--export-dynamic -Wl,--defsym,__ImageBase=0 -Wl,--gc-sections -Wl,--version-script=Enclave.lds")

SET(CMAKE_CXX_FLAGS "${CMAKE_C_FLAGS} -std=c++11 -nostdinc++")

add_executable(enclave.so ${enclave_srcs} ${edger_src} ${tlib_src})
