[cmake-developers] Canonical include pathes within ninja files

[Claus Klein]

Hi Peter,

I would like to know your opinion about Canonical path's

While testing with ninja generator, I found same rules with non  
Canonical include pathes.

a simple example from my test program:

"/tmp/some/deep/application/folder/../configuration/instance/../ 
instance/myfile.cfg"
"/tmp/some/deep/application/configuration/instance/myfile.cfg"
realpath -> /private/tmp/some/deep/application/configuration/instance/ 
myfile.cfg (which does not yet exists!)

see man realpath -- returns the canonicalized absolute pathname
http://www.kernel.org/doc/man-pages/online/pages/man3/realpath.3.html

Now the real questions:

1.) How can this done in a portable make insight cmake?
	I know only boost!

2.) And should it done?
	IMO yes! (It would be more clear and faster when we generate  
canonical path entries.)


//Regards
Claus Klein
