-# We define here 2 main variables : GMOCK_LINK and GMOCK_SRC
-#   for slc6, GMOCK_SRC will be empty
-#   for cc7 and later it's GMOCK_LINK that will be empty
-# If not empty, GMOCK_LIB is pointing to the gmock library
-# If not empty, GMOCK_SRC will contain the name of the gmock-all.cc
-# to be used (something like "/usr/src/gmock/gmock-all.cc")
-# Executables should use GMOCK_LIB AND GMOCK_SRC so that
-# compilation will work on all platforms
