[CMake] Did anyone manage to get incremental linking working with NMake generator?

It is not meant to be a command that is called by hand, so it might not 
have all the arguments it wants, and it crashed.  Not expected, but not 
that harmful either.

Are you building Release?  I think CMake only defaults to incremental 
builds for debug builds.  So, RELWITHDEBINFO and DEBUG build types will 
be the only ones that do this by default.

You would want to add the incremental flag to this cache variable to get 
CMake to link incrementally with release:
  CMAKE_EXE_LINKER_FLAGS_RELEASE

Yes, it does that for release builds, as the exe and dll files do not 
have the extra space needed for incremental linking.  Basically, CMake 
supports incremental and non-incremental linking.  If the 
/INCREMENTAL:YES flag is found then cmake -E vs_link_exe is used.  If 
not, then the non-incremental approach is taken.


All is working as expected.
