#
# 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
