1. Added the `inline` keyword to all functions in the `.cc` files. 2. Changed all anonymous namespaces to a named namespace (`detail`) in the `.cc` files. 3. Changed static class field to inline global variable. 4. Included the `.cc` file from its corresponding header file. An `INTERFACE` library has been added.

Very nice! I could imagine landing a change like this. Some comments:
| } // namespace detail | ||
|
|
||
| HWY_HEADER_ONLY_FUN | ||
| HWY_DLLEXPORT int Unpredictable1() { return timer::Start() != ~0ULL; } |

Might be worthwhile to merge these into a HWY_HEADER_ONLY_EXPORT?

Code Changes
To enable header-only mode, the following changes have been made:
inlinekeyword to all functions in the.ccfiles.detail) in the.ccfiles..ccfile from its corresponding header file.CMake Changes
An
INTERFACElibrary has been added.TODO
pre_target.ccfile is not yet completed, as it relies onfor_each.hwith some magical macros 😸.HWY_HEADER_ONLY_FUNmacro seems a bit clumsy; perhaps just using theinlinekeyword would be better.References
