# - try to find the argp library/component of glibc
#
# Users may optionally supply:
# ARGP_ROOT_DIR - a prefix to start searching.
#
# Cache Variables: (probably not for direct use in your scripts)
# ARGP_INCLUDE_DIR
# ARGP_LIBRARY, only defined if linking to an extra library is required
#
# Non-cache variables you might use in your CMakeLists.txt:
# ARGP_FOUND
# ARGP_INCLUDE_DIRS
# ARGP_LIBRARIES
#
# Requires these CMake modules:
# FindPackageHandleStandardArgs (known included with CMake >=2.6.2)
