[CMake] Re: another really basic question

[David Cole]

What page in the book...?

Try "LESS" instead of "less" (note the capital letters)

CMake is only semi-case-insensitive -- it used to be all uppercase all
the time. Lots of folks didn't like it, so the CMake guys made the
CMake *commands* work regardless of case, but some command args (like
LESS for the IF command) are still case sensitive.

CMake variable names are also case sensitive...

And ask qeuestions on the mailing list. Even if they seem silly. That
way everybody can benefit from the discussion. If you have the
question, somebody else will be wondering that same thing...

Good luck,
Dave
