# SYNOPSIS
#
# PDNS_CHECK_LIBPROMETHEUS([action-if-found[, action-if-not-found]])
#
# DESCRIPTION
#
# Look for prometheus-cpp library in standard places, or in a
# user-selected spot (via --with-libprometheus). Sets
#
# LIBPROMETHEUS_INCLUDES to the include directives required
# LIBPROMETHEUS_LIBS to the -l directives required
# LIBPROMETHEUS_LDFLAGS to the -L or -R flags required
#
# and calls ACTION-IF-FOUND or ACTION-IF-NOT-FOUND appropriately
#
# This macro sets LIBPROMETHEUS_INCLUDES such that source files should use the
# prometheus/ directory in include directives:
#
# #include <prometheus/registry.h>
