when building ext_seal,it occurs no type named 'index_type'

[L-coder148]

Hi, I install the library on ubuntu20.04. I run cmake .. -DCMAKE_CXX_COMPILER=clang++-6.0 -DNGRAPH_HE_ABY_ENABLE=ON, then run make install,when it comes to build ext_seal, it occurs the following error, I have installed GSL into the default location(/usr/local/) . The details are as follows

Sorry to bother you,I have another question.

1. I took the test_aby_relu circuit out of this repo, and put them into the repo ABY ABY/src/examples/relu as the following.

2. I install the ngraph and gtestinto /usr/local/ as libngraph.so and libgtest.a.

3. I added comments,such that aby_util.hpp and relu_aby.hp do not include hear file seal/he_seal_backend.hpp

4. mydefine.h is for ngraph/log, the code is as following #define PROJECT_ROOT_DIR "${CMAKE_SOURCE_DIR}"

5. the CMakeList.txt in the above picture is as following

   SET(NGRAPH_PATH "${PROJECT_SOURCE_DIR}/../../Github/ngraph")
   include_directories(${NGRAPH_PATH}/src)
   Link_DIRECTORIES("/usr/local/lib")
   add_executable(test_aby_relu test_aby_relu.cpp kernel/relu_aby.hpp  kernel/aby_util.hpp kernel/logging/ngraph_he_log.cpp kernel/logging/ngraph_he_log.hpp )
   target_link_libraries(test_aby_relu ABY::aby ENCRYPTO_utils::encrypto_utils libngraph.so gtest)

6. But when it links to the executable file,it occurs the undefined references to error. Hope for your guidance!
