When I wanted to use Julia in a C program using Clion and MinGW\_w64 compiler, an error occurred. I’ve written the cmakelists.txt of my project to include headers of Julia. The codes written are :  
`
set(INC_DIR C:/Julia/lang/Julia-1.0.0/include/julia)
include_directories(${INC_DIR})
`  
And the version of Julia installed is 1.0.

The error messages are:  
`

It is kind of wired that it suggested that the architecture of my computer is too old because I am using an 8th-gen Intel CPU.  
It seems that there’s no solution on Google. And I’ve asked for help on Chinese Julia discourse, but no one can figure it out.  
I hope someone can help me out. Thanks!
