Fix: disable "redundant move" warnings for GCC (#10803)

GCC warns about redundant std::move while clang warns when they are missing, so we silence the less harmful one

Codechange: [OSX] Prevent the compiler from using SSE4 instructions unless we want to.

This improves compatibility on older systems. We don't need to disable anything
older, as there are no SSE2-only Macs.

Fix 887b912af: MinGW requires an extra link flag with _FORTIFY_SOURCE (#8246)

see #7860

Codechange: Only apply FORTIFY_SOURCE in non-debug builds

It requires -O1 (or greater) and GCC spews out warnings if you try using it with -O0

Add: introduce CMake for project management

CMake works on all our supported platforms, like MSVC, Mingw, GCC,
Clang, and many more. It allows for a single way of doing things,
so no longer we need shell scripts and vbs scripts to work on all
our supported platforms.

Additionally, CMake allows to generate project files for like MSVC,
KDevelop, etc.

This heavily reduces the lines of code we need to support multiple
platforms from a project perspective.

Addtiionally, this heavily improves our detection of libraries, etc.
