# There exist several targets which are by default empty and which can be
# used for execution of your targets. These targets are usually executed
# before and after some main targets. They are:
# .build-pre: called before 'build' target
# .build-post: called after 'build' target
# .clean-pre: called before 'clean' target
# .clean-post: called after 'clean' target
# .clobber-pre: called before 'clobber' target
# .clobber-post: called after 'clobber' target
# .all-pre: called before 'all' target
# .all-post: called after 'all' target
# .help-pre: called before 'help' target
# .help-post: called after 'help' target
# Targets beginning with '.' are not intended to be called on their own.
# Main targets can be executed directly, and they are:
# build build a specific configuration
# clean remove built files from a configuration
# clobber remove all built files
# all build all configurations
# help print help mesage
# Targets .build-impl, .clean-impl, .clobber-impl, .all-impl, and
# .help-impl are implemented in nbproject/makefile-impl.mk.
# Available make variables:
# CND_BASEDIR base directory for relative paths
# CND_DISTDIR default top distribution directory (build artifacts)
# CND_BUILDDIR default top build directory (object files, ...)
# CONF name of current configuration
# CND_PLATFORM_${CONF} platform name (current configuration)
# CND_ARTIFACT_DIR_${CONF} directory of build artifact (current configuration)
# CND_ARTIFACT_NAME_${CONF} name of build artifact (current configuration)
# CND_ARTIFACT_PATH_${CONF} path to build artifact (current configuration)
# CND_PACKAGE_DIR_${CONF} directory of package (current configuration)

Answer 1

Which operating system are you using? If you are using Linux, which release of which distribution are you using?
The libraries named in your posting are Solaris system libraries. The Solaris linker knows where to find them.
