# The libjpeg-turbo build system has never supported and will never support
# being integrated into another build system using add_subdirectory(), because
# doing so would require that we (minimally):
#
# 1. avoid using certain CMake variables, such as CMAKE_SOURCE_DIR,
#    CMAKE_BINARY_DIR, and CMAKE_PROJECT_NAME;
# 2. avoid using implicit include directories and relative paths;
# 3. optionally provide a way to skip the installation of libjpeg-turbo
#    components when the 'install' target is built;
# 4. optionally provide a way to postfix target names, to avoid namespace
#    conflicts;
# 5. restructure the top-level CMakeLists.txt so that it properly sets the
#    PROJECT_VERSION variable; and
# 6. design automated regression tests to ensure that new commits don't break
#    any of the above.
#
# Even if we did all of that, issues would still arise, because it is
# impossible for an upstream build system to anticipate the widely varying
# needs of every downstream build system.  That's why the CMake
# ExternalProject_Add() function exists.  Downstream projects that wish to
# integrate libjpeg-turbo as a subdirectory should either use

  # Since v1.5.1, libjpeg-turbo uses the separate non-fancy upsampling and
  # YCbCr -> RGB color conversion routines rather than merged upsampling/color
  # conversion when fancy upsampling is disabled on platforms that have a SIMD
  # implementation of YCbCr -> RGB color conversion but no SIMD implementation
  # of merged upsampling/color conversion.  This was intended to improve the
  # performance of the Arm Neon SIMD extensions, the only SIMD extensions for
  # which those circumstances currently apply.  The separate non-fancy
  # upsampling and color conversion routines usually produce bitwise-identical
  # output to the merged upsampling/color conversion routines, but that is not
  # the case when skipping scanlines starting at an odd-numbered scanline.  In
  # libjpeg-turbo 2.0.5 and prior, doing that while using merged h2v2
  # upsampling caused a segfault, so this test validates the fix for that
  # segfault.  Unfortunately, however, the test also produces different bitwise
  # output when using the Neon SIMD extensions, because of the aforementioned
  # optimization.  The easiest workaround is to use the old test from
  # libjpeg-turbo 2.0.5 and prior when using the Neon SIMD extensions.  The
  # aforementioned segfault never would have occurred with the Neon SIMD
  # extensions anyhow, since merged upsampling is disabled when using them.
