install(EXPORT): Fail earlier if EXPORT is missing

Browse Source 
Add an explicit check in `install(EXPORT)` that the export name is
non-empty. Since an empty-named export set will never exist, this is
always an error. Previously, however, the error would not be caught
until generate time. Now an error will be produced immediately.
