#
|
|
# This procedure determines the PKG_OPTIONS that have been in effect
|
|
# when the package ${pkgbase} has been built. When the package is not
|
|
# yet installed, the current PKG_OPTIONS are queried.
|
|
#
|
|
# Parameters:
|
|
# pkgbase
|
|
# The basename of the package.
|
|
#
|
|
# Returns:
|
|
# PKG_BUILD_OPTIONS.${pkgbase}
|
|
# The build options of the package.
|
|
#
|
|
# Example:
|
|
# pkgbase := wine
|
|
# .include "../../mk/pkg-build-options.mk"
|
|
#
|
|
# Keywords: options pkg-build-options PKG_BUILD_OPTIONS
|
|

# whether BUILDLINK_TREE was empty or undefined, so defining it here
|
|
# avoids dealing one case.
