This is all rather interesting, and does look a bit broken to me.
The setup:
A file, foo.img with SHA256
b05528ba594ae4d6ca2b7b76ce02694e19a1c6d9d51b507e7b63d1919cb86e94. I
copy it to
smb://share.host/foo/bar/SHA256/b05528ba594ae4d6ca2b7b76ce02694e19a1c6d9d51b507e7b63d1919cb86e94.
Then map R: to smb://share.host/foo.
I put the following into my CMakeLists.txt:
~~~~
set(ExternalData_LINK_CONTENT "SHA256")
ExternalData_Expand_Arguments(fooimg fooimg_loc
DATA{bin/foo.img}
)
ExternalData_Add_Target(fooimg)
~~~~
Now, I try combinations of values for ExternalData_URL_TEMPLATES and
ExternalData_OBJECT_STORES:
Not working:
~~~~
list(APPEND ExternalData_URL_TEMPLATES "\\\\share.host/foo/bar/%(algo)/%(hash)")
~~~~
The file is not found.
Working:
~~~~
list(APPEND ExternalData_URL_TEMPLATES "\\\\share.host/foo/bar/%(algo)/%(hash)")
list(APPEND ExternalData_OBJECT_STORES "r:/bar")
~~~~
The file is apparently found (at least there's no complaint) but then
taken from the store.
Not working:
~~~~
list(APPEND ExternalData_URL_TEMPLATES "\\\\share.host/foo/bar/%(algo)/%(hash)")
list(APPEND ExternalData_OBJECT_STORES "\\\\share.host/foo/bar")
~~~~
The file is not found.
Not working:
~~~~
list(APPEND ExternalData_OBJECT_STORES "r:/bar")
~~~~
Complains that ExternalData_URL_TEMPLATES is empty.
I was surprised to find that ExternalData_URL_TEMPLATES and
ExternalData_OBJECT_STORES weren't more independent and it's
disappointing to find that it isn't possible to use an UNC path to
download a data object.
