[Cmake] Dependency checker, custom command, and Intel C++ compiler

[Miller, James V (CRD)]

I have been having a hard time lately with CMake projects that use the Intel C++ compiler.  The
problem is an "undefined symbol" encountered at link time.  It always relates to a change made to a
header file in another directory.  In other words, a change is made to a header file in one directory
and an xecutable that "implicity" needs that new header (i.e. it does not include the file itself but
something it includes needs the file) fails to link because it cannot find the "new" symbol.
 
I have had this happen when I moved a method from the protected section of a class to the private
section of a class.  I have had this happen when I add an ivar to class.
 
This problem never occurs when the VC++ compiler is used, only when the Intel C++ compiler is used as
a drop in replacement to the VC++ compiler. Does anyone know if there is a known problem with the
DevStudio dependency checker when the Intel C++ compiler is used? Could this be a problem with
"when/how" custom commands are run?
 
My only recourse is to clean the entire workspace and have CMake regenerate the project files.  This
is rather a pain.
