[CMake] Trouble with CMake + Eclipse + SVN/CVS

[Mike Jackson]

I agree that there are some conflicting philosophies here. I am a bit  
more practical about this. I just need to get my work done.

CMake's philosophy of "out-of-source" builds is great. I agree with  
it whole heartedly. The problem is that this does not always work in  
the world we live in. I can get "pretty close" to out-of-source  
builds by creating the "Build" folder within the source. It is easy  
enough to put this folder on a CVS ignore list. As for the eclipse  
project files, same thing goes for those. I put them on the CVS  
ignore list and don't worry about it. CDT projects do not usually  
work for my team for several reasons so we do not use them.
   Most most people the out-of-source build strictness is OK. For the  
rest of us, CMake is just flexible enough to allow me to create a  
programming environment and workflow that "works for me". If it works  
for others then great. If it does not, then fine. I at least like to  
make those new to Eclipse+CDT+CMake aware that there are scenarios  
that _do_ work.

   Also, I can accept having the eclipse project files clutter my  
project tree because:
	1: There are 2 or 3 of them ONLY. They are well defined and easy to  
get rid of or put on the CVS ignore list
	2: Cmake creates lots more than 2 or 3. Having these sandboxed into  
a "Build" folder is acceptable to me.

I _do_ advocate at least a "Build" directory if someone _really_  
wants to build inside the source tree. Usually by getting them to  
just listen to the logic is enough to get them to change. It is not  
hard to say "Look at all those build files. Wouldn't it be nice if  
all those were sandboxed somewhere else?".

Just my 2 cents to help make others aware that there are "other" ways  
to use Cmake that end up working just fine.

Peace.
