-# -------------------------------------------------------------------
-#
-# Define an option.
-#
-# The option may have different types, it can be STRING, PATH, BOOL and FEATURE,
-# it will create cache variables using set() or option depending on the type.
-#
-# General invocation takes the following arguments:
-#
-# define_option(
-#   NAME variable name
-#   TYPE BOOL | FEATURE | PATH | STRING
-#   DOC (Optional) option description
-#   DEFAULT (Optional) default value
-# )
-#
-# Some types can takes more arguments, see below the following sections.
-#
-# ## String and paths
-#
-# If type is set to PATH, an additional ${NAME}_ABS variable is defined as the
-# absolute directory to CMAKE_INSTALL_PREFIX if the value is relative.
-#
-# Example:
-#
-# if an option WITH_DOCDIR is of type PATH and set to "share/doc", the variable
-# WITH_DOCDIR_ABS will be set to CMAKE_INSTALL_PREFIX/share/doc.
-#
-# ## Booleans
-#
-# If type is set to BOOL, an additional variable ${NAME}_MSG is set to "Yes" or
-# to "No" depending if the option value is set.
-#
-# If no default value is given, it is set to On.
-#
-# Example:
-#
-# If an option WITH_FOO is of type BOOL and set to On, WITH_FOO_MSG will be set
-# to "Yes".
-#
-# ## Features
-#
-# The FEATURE type is a superset of BOOL. It is designed to check if an option
-# is enabled and able to build. For example, the user requests the feature
-# 'abc' but can't be enabled because the system lacks missing tools.
-#
-# If no default value is given, it is set ${CONDITION}.
-#
-# The command may take the new following extra arguments:
-#
-#   - CONDITION The condition to enable the feature,
-#   - CONDITION_MESSAGE (Optional: default "${OPT_NAME} not found") the reason
-#     to set if the condition is not matched,
-#   - DISABLED_MESSAGE (Optional: default: "${OPT_NAME} disabled by user") the
-#     reason when the option has been disabled by the user.
-#
-# This command create the same variables as BOOL type. It adds also
-# ${NAME}_ENABLED variable which is set to On if both ${CONDITION} and ${NAME}
-# are set to On.
-#
-# Example:
-#
-# find_package(OpenSSL)
-#
-# define_option(
-#   NAME SSL
-#   TYPE FEATURE
-#   CONDITION ${OPENSSL_FOUND}
-#   CONDITION_MESSAGE "OpenSSL not found"
-#   DISABLED_MESSAGE "OpenSSL disabled by user"
-# )
-#
-# By default, if OpenSSL is not found and SSL kept to On, SSL_ENABLED will be
-# set to Off and SSL_MSG will be set to "OpenSSL not found".
-#
-# If SSL is set to Off, SSL_ENABLED will be set to Off and SSL_MSG set to
-# "OpenSSL disabled by user".
