  1. # - try to find the OpenAL ALUT library
  2. #
  3. # Users may optionally supply:
  4. # ALUT_ROOT_DIR - a prefix to start searching.
  5. #
  6. # Cache Variables: (probably not for direct use in your scripts)
  7. # ALUT_INCLUDE_DIR
  8. # ALUT_LIBRARY
  9. #
  10. # Non-cache variables you might use in your CMakeLists.txt:
  11. # ALUT_FOUND
  12. # ALUT_INCLUDE_DIRS
  13. # ALUT_LIBRARIES
  14. # ALUT_WORKAROUND_INCLUDE_DIRS - add these to your include path with
  15. # include_directories(${ALUT_WORKAROUND_INCLUDE_DIRS} ${ALUT_INCLUDE_DIRS})
  16. # so you can always #include <AL/al.h> and #include <AL/alut.h> even on
  17. # Mac where the paths might differ.
  18. #
  19. # Requires these CMake modules:
  20. # FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
