Dear Bruno,
You need to specify appropriate CXX flags. For example, I always use
-D CMAKE_CXX_FLAGS="-march=native"
on my local machines (that run the code I'm compiling) or
-D CMAKE_CXX_FLAGS="-march=icelake-server"
on clusters to be sure the right code gets generated. For example GCC
lists the available architectures to specify here:
https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html
Best,
Martin

Dear all,
Hope you are well.
I have tried a few ways to enable AVX instructions (which I think my
12th Gen Intel(R) Core(TM) i9-12900K) should support, yet I am always
unable to do so. At the Cmake configuration step, the AVX steps all
fails whereas the SSE ones succeed.
How can I remedy this issue?
Best
Bruno
