That'll work. You're missing the variable type from your set statement.
You have to give all three of "CACHE TYPE DOCSTRING" if you want to set
a cache variable.<br>
<br>
Use this instead and the rest should be ok:<br>
SET ( PROJ_README "${PROJECT_SOURCE_DIR}/README.txt"
<br>
CACHE <b><font color="#ff0000">STRING</font></b> "Where to find a
project's README file"
<br>
)

I'm pretty much expecting to be told, "Can't get there from here", but
I'd like to set a variable in a top-level project in terms of another
variable which may change. I'd then like to refer to that variable at a
lower level and have it expanded at the time of evaluation.
<br>
<br>
For example:
<br>
<br>
PROJECT ( TOP )
<br>
SET ( PROJ_README "${PROJECT_SOURCE_DIR}/README.txt"
<br>
CACHE "Where to find a project's README file"
<br>
)
<br>
SUBDIRS ( BOTTOM )
<br>
<br>
Followed by:
<br>
<br>
PROJECT ( BOTTOM )
<br>
MESSAGE ( STATUS "PROJ_README = ${PROJ_README}" )
<br>
<br>
Is this even possible?
<br>
<br>
Thanks,
<br>
Chris.
