for handling per-package build options.
Before including this file, the following variables should be defined:
PKG_OPTIONS_VAR
This is a list of the name of the make(1) variables that
contain the options the user wishes to select. This
variable should be set in a package Makefile. E.g.,
PKG_OPTIONS_VAR= WIBBLE_OPTIONS
or
PKG_OPTIONS_VAR= FOO_OPTIONS BAR_OPTIONS
PKG_SUPPORTED_OPTIONS
This is a list of build options supported by the package.
This variable should be set in a package Makefile. E.g.,
PKG_SUPPORTED_OPTIONS= kerberos ldap ssl
Optionally, the following variables may also be defined:
PKG_DEFAULT_OPTIONS
This is a list the options that should be built into
every package, if that option is supported. This
variable should be set in /etc/mk.conf.
${PKG_OPTIONS_VAR} (the variables named in PKG_OPTIONS_VAR)
These variables list the selected build options and
override any default options given in PKG_DEFAULT_OPTIONS.
If any of the options begin with a '-', then that option
is always removed from the selected build options, e.g.
PKG_DEFAULT_OPTIONS= kerberos ldap sasl
PKG_OPTIONS_VAR= WIBBLE_OPTIONS
WIBBLE_OPTIONS= ${PKG_DEFAULT_OPTIONS} -sasl
# implies PKG_OPTIONS == "kerberos ldap"
or
PKG_OPTIONS_VAR= WIBBLE_OPTIONS
WIBBLE_OPTIONS= kerberos -ldap ldap
# implies PKG_OPTIONS == "kerberos"
This variable should be set in /etc/mk.conf.
PKG_FAIL_UNSUPPORTED_OPTIONS
If this is set to "yes", then the presence of unsupported
options in PKG_OPTIONS.<pkg> (see below) causes the build
to fail. Set this to "no" to silently ignore unsupported
options. Default: "yes".
After including this file, the following variables are defined:
PKG_OPTIONS
This is the list of the selected build options, properly
filtered to remove unsupported and duplicate options.
