Do not link to 'm' explicitly

[roversch]

MSVC is failing with following message:

Please do not link explicitly to m in CMake, because it does not exist on Windows systems.

The files which require linking to the m (Math) library are the examples of BLASFeo.
So if you set the flag BLASFEO_EXAMPLES to OFF the compilation will be successful.

@giaf , I think a solution for the mean time would be setting BLASFEO_EXAMPLES to OFF on Windows.

Thanks for the suggestion, I will look into it.
I'm much more familiar with make thank cmake.

Actually both are not that good in my opinion.
If you're open to try something new and more flexible, try Meson.
