easy_config 问题

[Quitino]

- gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~18.04) 
- cmake version 3.15.3

catkin_make 时报错：

[ 28%] Generating _ezcfg_gen_code/_ezcfg_gen_file.cpp
/bin/sh: 1: path2project/build/fusion-based-perception/easy_config/_ezcfg_gen_code/_ezcfg_gen_file.cpp: not found

我尝试了阅读cmake部分：

    add_custom_command(
      OUTPUT ${GEN_FILE}
      COMMAND compiler ${EZCFG_STRUCT_HEADER_FILE_RELATIVE} ${GEN_FILE}
      # COMMENT "Running compiler"
      WORKING_DIRECTORY ${CMAKE_SOURCE_DIR}
      DEPENDS compiler
    )

未发现什么异常，当我手动建立 _ezcfg_gen_file.cpp空文件到指定位置后编译，链接报错：

想咨询一下这个问题是出在哪里啊我的编译环境：

- gcc version 9.4.0 (Ubuntu 9.4.0-1ubuntu1~18.04) 
- cmake version 3.15.3

是cmake 版本问题吗？ 希望解答，谢谢了。
