# It is important to identify the version of 'javadoc' being utilized since
# different versions support different options.
#
# While 'cmake' contains numerous built-in references to the 'java' version,
# it contains no built-in references to either the 'javac' or 'javadoc'
# versions, and unfortunately, the specified version of 'java' may be
# different from the specified versions of 'javac' and 'javadoc'.
#
# Additionally, although 'javadoc' contains no command-line option to identify
# its version, it is important to note that 'javadoc' is supplied by the same
# package that supplies 'javac', and although multiple versions of these
# executables could co-exist on the same system, it is relatively safe to
# assert that the currently specified 'javac' and 'javadoc' will be the same
# version.
#
# As an example in support of this assertion, on systems which utilize
# '/usr/sbin/alternatives', setting the 'javac' version will also
# automatically set the 'javadoc' version to match the 'javac' version, and
# 'usr/sbin/alternatives' cannot be used to set a specific 'javadoc' version.
#
# Therefore, regardless of the 'java' version, this 'CMakeLists.txt' file will
# programmatically utilize the invoked 'javac' version information (output is
# to stderr) in order to correctly identify the supported 'javadoc' options:
#
#     # javac -version 2>&1 | awk -F \. '{printf $2}'
#
# NOTE:  Used 'cut' instead of 'awk' due to 'cmake' parsing limitations:
#
#     # javac -version 2>&1 | cut -f2 -d.
