# @VARIABLE: NUMERIC_MODULE_NAME
# @DESCRIPTION:
# The base pkg-config module name of the package being built.
# NUMERIC_MODULE_NAME is used by the numeric-int64_get_module_name to
# determine the pkg-config module name based on whether the package
# has dynamic, threads or openmp USE flags and if so, if the user has
# turned them or, and if the current multibuild is a int64 build or not.
#
# @CODE
# NUMERIC_MODULE_NAME="openblas"
# inherit ... numeric-int64-multibuild
# @CODE
: ${NUMERIC_MODULE_NAME:=blas}
# @FUNCTION: create_pkgconfig
# @USAGE: [ additional arguments ]
# @DESCRIPTION:
# Creates and installs pkg-config file. The function should only be executed in
# src_install(). For further information about optional arguments please consult
# http://people.freedesktop.org/~dbn/pkg-config-guide.html
#
# @CODE
# Optional arguments are:
#
# -p | --prefix Offset for current package (${EPREFIX}/usr)
# -e | --exec-prefix Offset for current package (${prefix})
# -L | --libdir Libdir to use (${prefix}/$(get_libdir))
# -I | --includedir Includedir to use (${prefix}/include)
# -n | --name A human-readable name (PN}
# -d | --description A brief description (DESCRIPTION)
# -V | --version Version of the package (PV)
# -u | --url Web presents (HOMEPAGE)
# -r | --requires Packages required by this package (unset)
# -l | --libs Link flags specific to this package (unset)
# -c | --cflags Compiler flags specific to this package (unset)
# --requires-private Like --requires, but not exposed (unset)
# --conflicts Packages that this one conflicts with (unset)
# --libs-private Like --libs, but not exposed (unset)
