[CMake] Re: ADD_SUBDIRECTORY and EXCLUDE_FROM_ALL

[DA]

Hi,

I figured this out on my own. Apparently if the CMakeLists.txt file in the 
mentioned sub-directoy contains a INSTALL rule, the EXCLUDE_FROM_ALL 
parameter does not apply. If I add the "OPTIONAL" directive to the INSTALL 
target, then all works as advertised.

The question I now have is that should it matter if the CMakeLists.txt of the 
subdirectory I include contains an INSTALL target ? Somehow to me it does not 
make sense. When I added EXCLUDE_FROM_ALL, I expected that directory to be 
excluded regardless of the target I built: "make all" or "make install". 
Otherwise, it would be nice if the documentation for ADD_SUBDIRECTORY stated 
this little fact...

Thanks.
