Clang Code Model has issues when OpenMP is enabled (CMake)

      When I use the Armadillo libary and enable OpenMP, the Clang Code Model gives me a lot of errors in the IDE, but compilation works fine.

      Here is a minimal example

      cmake_minimum_required(VERSION 2.8)

project(test-qtcreator-openmp-arma)
add_executable(${PROJECT_NAME} "main.cpp")

find_package(Armadillo REQUIRED)
target_include_directories(${PROJECT_NAME} PRIVATE ${ARMADILLO_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${ARMADILLO_LIBRARIES})

FIND_PACKAGE(OpenMP REQUIRED)
target_link_libraries(${PROJECT_NAME} OpenMP::OpenMP_CXX)

      #include <armadillo>

int main()
{
    arma::vec v;
    return 0;
}

      This shows the error `no type named 'vec' in namespace 'arma'` on line 5, but compiles just fine. This can get pretty annoying when arma is used everywhere, and has made me disable the Clang Code Model completely for such projects.
