dnl AM_PATH_LD10K1([MINIMUM-VERSION [, ACTION-IF-FOUND [, ACTION-IF-NOT-FOUND]]])

dnl Test for liblo10k1, and define LD10K1_CFLAGS and LD10K1_LIBS as appropriate.

dnl enables arguments --with-ld10k1-prefix=

dnl For backwards compatibility, if ACTION_IF_NOT_FOUND is not specified,

dnl and the ld10k1 libraries are not found, a fatal AC_MSG_ERROR() will result.
