Build: Fail if included with add_subdirectory() Even though BUILDING.md and CONTRIBUTING.md explicitly state that the libjpeg-turbo build system does not and will not support being integrated into downstream build systems using add_subdirectory() (see 05655481917a2d2761cf2fe19b76f639b7f159ef), people continue to file bug reports, feature requests, and pull requests regarding that (see #265, #637, and #653 in addition to the issues listed in 05655481917a2d2761cf2fe19b76f639b7f159ef.) Responding to those issues wastes our project's limited resources. Hopefully people will get the hint if the build system explicitly tells them that it can't be included using add_subdirectory(), which will prompt them to read the comments in CMakeLists.txt explaining why. To anyone stumbling upon this commit message, please refer to the discussions under the issues listed above, as well as the issues listed in 05655481917a2d2761cf2fe19b76f639b7f159ef. Our project's position on this has been stated, explained, and defended numerous times.
