cmake 的时候提示找不到add_compile_definitions

[PeterXiaTian]

如题，在cmake的时候提示找不到下面的宏，请问是什么原因？

-- The CXX compiler identification is GNU 7.5.0 -- Check for working CXX compiler: /usr/bin/c++ -- Check for working CXX compiler: /usr/bin/c++ -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done -- Detecting CXX compile features -- Detecting CXX compile features - done -- USE_CUDA: ON -- PYTHON_API: OFF -- USE_SENTENCEPIECE: OFF -- CMAKE_CXX_FLAGS -pthread --std=c++17 -O2 -march=native -- The CUDA compiler identification is NVIDIA 11.3.109 -- Check for working CUDA compiler: /usr/local/cuda/bin/nvcc -- Check for working CUDA compiler: /usr/local/cuda/bin/nvcc -- works -- Detecting CUDA compiler ABI info -- Detecting CUDA compiler ABI info - done CMake Error at CMakeLists.txt:50 (add_compile_definitions): Unknown CMake command "add_compile_definitions".

是不是gcc,cmake的版本不兼容所致？

请问您使用的cmake是什么版本？早期 (<3.12) 版本的cmake不支持这个命令，参考这里

应该是CMake版本比较老，需要升级一下
