How to use precompiled headers in CMake project in QtCreator?

Alexander Trots

Hello
I trying to use a precompiled header in CMake project. Cotire module provides this functionality. But QtCreator code highlight not working. It seems that QtCreator code model doesn't parse a precompiled header.
Here is a project example:

CMakeLists.txt

include(cotire)

cmake_minimum_required(VERSION 2.8)

project(temp_cmake_precompiled)
add_executable(${PROJECT_NAME} "main.cpp")

set_target_properties(${PROJECT_NAME} PROPERTIES COTIRE_CXX_PREFIX_HEADER_INIT "Stable.h")
cotire(${PROJECT_NAME})

main.cpp

int main()
{
  std::vector<int> vec;
  std::cout << vec.size() << std::endl;
  return 0;
}

Stable.h

#include <iostream>
#include <vector>

Both Clang and built-in code model have this problem. But build performs with success.
In dialog Tools -> C++ -> Inspect C++ Code Model... a Precompiled headers key is set to <None>.

May be there is a different way to specify a precompiled header in CMake project that QtCreator can resolve?

QtCreator 4.8.2

I ran into the same problem and this problem is very very annoying during daily work.

I filed a bug report for that issue.
