Sounds logical and it is what I expect, very good :)

I remove my 2.4.3 install and use now the freshly released 2.4.6.

The "out.txt" attachment is the ouput of the CMakeLists.txt.  I simply
added a printf in cmMakefile::GetModulesFile, in the true clause of
"if(cmSystemTools::FileExists(itempl.c_str()))".

I was wrong when I said that cmake did not find or do not use the
default path, it does.  But the macros is not defined. If I add
include(CheckIncludeFile), it works. I wonder what I broke (as it
seems to work for anyone else) as it is now a fresh install from the
official 2.4.6 sources package. Any idea?

As a workaround, I will a file to include all macros I need. It's ugly
but it will work.

It is set correctly.
