Usage

sst-filters is a header-only library, so it is possible to use the library simply by adding include/ to your header search paths, and writing #include <sst/filters.h> somewhere in your source code. However, it is recommended to use the provided CMake configuration.

add_subdirectory(path/to/sst-filters)
target_link_libraries(My-Killer-App PUBLIC  sst-filters)

Note: the sst-filters library uses raw SSE SIMD intrinsics. If you are planning to use this library in a context that may not support SSE intrisics, it is recommended to also link with simde.
