[CMake] "NMake Makefiles" generator complains about missing internal variable CMAKE_RC_LINK_EXECUTABLE

[David Cole]

CMake uses the "language" of the source files compiled for an executable to
determine what variable to use for the link stage... So, in the normal C++
case, CMAKE_CXX_LINK_EXECUTABLE would be used.

In the general case, where an executable is built solely with "language"
source files, the variable CMAKE_${language}_LINK_EXECUTABLE is used to
compute the link command.

You could try this prior to your ADD_EXECUTABLE call:
SET(CMAKE_RC_LINK_EXECUTABLE "${CMAKE_CXX_LINK_EXECUTABLE}")

Or you could try adding an empty "dummy.cxx" file to your ADD_EXECUTABLE
command.

HTH,
David
