# libo_MINGW_CHECK_DLL(dll-name-stem,[action-if-found],[action-if-not-found])
#
# Checks for presence of dll dll-name-stem . Appends the dll name to
# variable MINGW_DLLS if found, issues an error otherwise.
#
# It recognizes these dll patterns (x, y match any character, but they
# are supposed to be numerals):
# * name-x.dll
# * name-xy.dll
# * name-x.y.dll
# * name.dll
#
#
# Example:
# MINGW_DLLS=
# libo_MINGW_CHECK_DLL([libexpat])
# might result in MINGW_DLLS containing libexpat-1.dll .
#
# uses MINGW_SYSROOT, WITH_MINGW
# changes MINGW_DLLS
