(Regression introduced by 24e09baaf0)
The install() INCLUDES option is not an artifact option. It specifies
a list of directories that will be added to the
INTERFACE_INCLUDE_DIRECTORIES target property when the target is
exported using the install() EXPORT option, which occurs when CMake
package config files are generated. Specifying 'COMPONENT include' with
the install() INCLUDES option caused the INTERFACE_INCLUDE_DIRECTORIES
properties in our CMake package config files to contain
'${_IMPORT_PREFIX}/COMPONENT', which caused errors of the form 'Imported
target "libjpeg-turbo::XXXX" includes non-existent path' when downstream
build systems attempted to include libjpeg-turbo using find_package().
