Here's an SSCCE that demonstrates the problem with Vc 0.7.4:

  cmake_minimum_required(VERSION 3.0)
  project(VcTest)

  set(CMAKE_INCLUDE_CURRENT_DIR ON)

  find_package(Qt5Core REQUIRED)
  find_package(Vc REQUIRED)

  # Uncomment this to make the build work
  # include_directories(${Qt5Core_INCLUDE_DIRS})

  vc_compile_for_all_implementations(__per_arch_factory_objs
    hello.cpp 
    FLAGS -fPIC ONLY SSE2)

  message("Following objects are generated from the per-arch lib:

    ${__per_arch_factory_objs}

  ")

  add_executable(hello ${__per_arch_factory_objs})
  target_link_libraries(hello Qt5::Core)



At first, I did not get a build failure because I used Vc from the master 
branch. Commit b23418cd (change vc_compile_for_all_implementations macro to 
use normal cmake compilation, 2013-10-05) removed the code which reads the 
INCLUDE_DIRECTORIES directory property.

That fact gives you more options for a way forward, right?

Thanks,

Steve.
