be creative! ;-)

  import std.algorithm, std.stdio;

  void main () {
    string fname = "hello.exe";
    import std.path : extension;
    if (findAmong([fname.extension], [".exe", ".lib", ".a", ".dll"]).length) {
      writeln("got it!");
    } else {
      writeln("alas...");
    }
  }

note the dots in extension list.

yet you can do it even easier:

  import std.algorithm, std.stdio;

  void main () {
    string fname = "hello.exe";
    import std.path : extension;
    if ([".exe", ".lib", ".a", ".dll"].canFind(fname.extension)) {
      writeln("got it!");
    } else {
      writeln("alas...");
    }
  }

as you obviously interested in extension here -- check only that
part! ;-)
