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.
To build and run the sst-filters unit tests:
cmake -Bbuild
cmake --build build
./build/test-binary/sst-filters-tests
To build the sst-filters examples:
cmake -Bbuild -DSST_FILTERS_BUILD_EXAMPLES=ON
cmake --build build
Example binaries will be located in build/example-binaries/
