a good way to disallow in-source builds? Ideally, I’d like to prevent it
before any cruft is written into the source tree. I experimented with writing
a function into my CMakelists file and calling it. The function checked if
CMAKE_BINARY_DIR was equal to CMAKE_SOURCE_DIR and messaged a FATAL_ERROR if
that was the case. This works ok, but still generates a CMakeFiles directory
and a CMakeCache.txt file.</span></font></b></p></div></div></blockquote><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;"><div lang="EN-US" link="blue" vlink="purple">

second half of the question is of course, is there an easy way to clean out a

dividing the files by their timestamp and removing the newer ones, etc..)</span></font></b></p></div></div></blockquote><div><br></div><div><div>CMake doesn't have a command to clean up after itself which seems to be what you're asking for (it would help for both use-cases you specify).
