cmake include path still not working

[echoface]

cmake project still can't export its include dir;

cmake_minimum_required(VERSION 3.14 FATAL_ERROR)

project(llhttpexe VERSION 0.2.1 LANGUAGES C CXX)

# for generate ycm complete database
SET(CMAKE_CXX_STANDARD 14)
SET(CMAKE_EXPORT_COMPILE_COMMANDS ON)

include(FetchContent)

add_executable(main
    main.cc)

target_link_libraries(main
    llhttp_shared)    

#include "llhttp.h"
#include "stdio.h"
#include "string.h"

int handle_on_message_complete(llhttp_t *parser) {
  fprintf(stdout, "Message completed!\n");
  return 0;
}

int main() {
  llhttp_t parser;
  llhttp_settings_t settings;

  int request_len = strlen(request);

  enum llhttp_errno err = llhttp_execute(&parser, request, request_len);
  if (err == HPE_OK) {
    fprintf(stdout, "Successfully parsed!\n");
  } else {
    fprintf(stderr, "Parse error: %s %s\n", llhttp_errno_name(err), parser.reason);
  }
}

according to cmake generated output, no correct -Ixxxx/include/path to main.cc compiler command

{
  "directory": "/home/echoface/code/llhttpexe/build",
  "command": "/usr/bin/c++   -O2 -g -DNDEBUG -std=gnu++14 -o CMakeFiles/main.dir/main.cc.o -c /xxxxx/llhttpexe/main.cc",
  "file": "/xxxx/llhttpexe/main.cc"
},

This has been solved in #226 which is included in llhttp 9.0.0.
Can you upgrade to 9 (if you spec complaint it will mean no breaking changes to you) or do you need a backport?
