CMAKE_FIND_LIBRARY_SUFFIXES

Suffixes to append when looking for libraries.

This specifies what suffixes to add to library names when the find_library() command looks for libraries. On Windows systems this is typically .lib and, depending on the compiler, .dll.lib, .dll.a, .a (e.g. rustc, GCC, or Clang), so when it tries to find the foo library, it will look for [<prefix>]foo[.dll].lib and/or [<prefix>]foo[.dll].a, depending on the compiler used and the <prefix> specified in the CMAKE_FIND_LIBRARY_PREFIXES.
