The implementation of `install(EXPORT)` generates files into a staging directory for later installation. We use the full install destination in the path to the staging directory to avoid collisions. In order to avoid exceeding maximum path lengths (especially on Windows) we compute a hash of the install destination when it is too long. Fix this logic to account for the length of the file name(s) when deciding whether to switch to the hashed name. Reported-by: Alan W. Irwin <irwin@beluga.phys.uvic.ca>
