软件编译出现fatal error: mpi.h: No such file or directory解决办法

软件编译时，如果出现fatal error: mpi.h: No such file or directory的问题时，很大可能是你的环境变量路径没有设置好，解决思路如下：

export CPATH=/opt/intel/impi/2019.0.117/intel64/include:$CPATH

export LD_LIBRARY_PATH=/opt/intel/impi/2019.0.117/intel64/lib:$LD_LIBRARY_PATH

如果是使用oneapi intel编译的话，路径则为

export CPATH=/opt/intel/oneapi/mpi/2021.9.0/include:$CPATH

export LD_LIBRARY_PATH=/opt/intel/oneapi/mpi/2021.9.0/lib/release:$LD_LIBRARY_PATH
