I was building an external library called jolt physics, I got an error that was hard to debug because I didn't have enough knowledge about my tools I was getting that _mm_cvtss_f32 was not defined and saw that it mentioned something called -msse4.1 I read about what that is and apparently it's a CPU extension for those cpus that support it sse
Apparently my cpu supports it which I checked by seeing what optimizaitons my gcc had:
$ gcc -Q --help=target | grep msse4.1
-msse4.1 [disabled]
You can just pass the -msse4.1 flag to gcc when compiling to turn it on, but I use conan for package management, so I had to do update my conan profile to something like this:
...
[conf]
tools.build:cflags=["-msse4.1"]
tools.build:cxxflags=["-msse4.1"]
By default you cannot simply just do a conan install . --profile=debug as that will not rebuild all your packages, in order to do that I had to run conan install . --profile=debug --build=*
