add_library(heaan INTERFACE)
target_link_libraries(heaan INTERFACE HEaaN::HEaaN)

# Add subdirectories
add_subdirectory(src)

# Add tests and examples (optional)
option(BUILD_TESTS "Build tests" OFF)
option(BUILD_EXAMPLES "Build examples" OFF)

if(BUILD_TESTS)
    add_subdirectory(tests)

# Include CUDA headers if needed
include_directories("/usr/local/cuda/include")

# Create executable
add_executable(my_program ${SOURCES}

cmake/BuildType.cmake
