FYI: I used this because specifying -mavx2 -mbmi2 like the script is doing for regular GCC/Clang wasn't enough. I got the following error about missing lzcnt support, and using -march=haswell fixed it:
src\BasicMath.cpp(2154,46): error : always_inline function '_lzcnt_u64' requires target feature 'lzcnt', but would be inlined into function 'PossiblyUpcast' that is compiled without support for 'lzcnt'

Ugh, sorry, I missed this comment before merging. Next time I'm poking around in here I'll fix the indentation.

While trying to work out a compile error for #120 when compiling with Linux/GCC, I tried compiling with
clang-cland MSVC to see if I could easily reproduce the error that way. I wasn't quite able to get riptide_cpp to compile withclang-cl(and VS 2022.0), but I did make some progress towards getting it compiling -- mainly I needed to add the existing compile options for Clang to the options forclang-cl(detected as MSVC + Clang).It might be useful to set up a clang-cl build for riptide_cpp in the future. To that end, I'm submitting the CMakeLists.txt changes I tried, so when someone has time to sort out the remaining issue(s) they'll have a better starting point.
The remaining issues I see when attempting to compile:

One other thing that surprised me (that seems worth investigating) -- even though the root CMakeLists.txt in the repo specifies the C++17 standard is required and that's respected when building with MSVC, building with clang-cl (via
python setup.py build) doesn't appear to respect the setting and falls back to compiling with C++14. I'm using CMake 3.22.1 in case it matters. From one build log:Details
