Hello All,
It is is because of
# AUX_SOURCE_DIRECTORY(. DIR_TARGET)
# ADD_LIBRARY (relfiles ${DIR_TARGET})
That’s really a stupid fault ,and thanks for your debug …TAT
I adjust the usage of External project , and it seems much better .
Thanks for your help . Thanks for Micha Hergarden’s patience …
By the way ,
set_property(TARGET leveldb_proj PROPERTY EXCLUDE_FROM_ALL TRUE)
I removed this property and it seems still works.
