<p class=MsoNormal>Your build system would be independent where the output
files are: the user can choose whatever build directory they want, and not be
limited to _gnuDebug and _gnuRelease. (If they so chose, they could
create each of those and configure a build into them, but they are just as
likely to not do so. Actually, as I look at your info again, it looks like
you're making lots of those _gnuRelease directories - that definitely looks
like an in-source build.) If that's a policy you want to encourage in
your organization, that's just fine, but to CMake, you should keep things
relative to CMAKE_SOURCE_DIR/CMAKE_CURRENT_SOURCE_DIR and CMAKE_BINARY_DIR/CMAKE_CURRENT_BINARY_DIR.
The general guideline is to never modify or generate anything into the
_SOURCE_DIR - only into the _BINARY_DIR, that way you can get back to a clean
source tree by just deleting the build directory. The makefiles generated
by CMake will all be in the binary directory (and as a preemptive warning:
don't commit the generated makefiles to source control, they are not
machine-independent), so that's where you'd run make.<o:p></o:p></p>

<p class=MsoNormal>Ok, I'm trying to think of how this would work for us.<br>
<br>
The source for each of our libraries is in a separate subdirectory as you would
expect. The subdirectory structure is:<br>
<br>
Subdir ----- .cpp files<br>
|<br>
|-- Makefile<br>
|<br>
|-- _gnuDebug <=== .o and .a
files for Debug build<br>
|<br>
|-- _gnuRelease <=== .o and .a
files for Release build<br>
<br>
Would you call that an out-of-source build, or would you require the Makefile
to be in a 'Build' subdirectory below the source?<br>
<br>
Or, would you really like to see the build files somewhere to the side of the
source files?<o:p></o:p></p>
