This is probably a pretty good workaround, but it's not ideal because I have 
several projects that add this directory, and I only want it to be excluded 
for some of them.  So I'll end up needing to use a variable in the parent 
directory to control the EXCLUDE_FROM_ALL property.  Then I need to use the 
OPTIONAL argument to prevent errors if I haven't built the directory, which 
means I won't be notified if a file is missing.

What I'd really like to be able to do, is add new targets, and then manually 
set them to depend on whichever install commands I want.  Then I could just 
run: make install/my_exclude_from_all_project.  But it seems that the install 
commands are outside of the target system.
