When a CMake domain 'command' object is defined by CMakeTransform or the 'cmake:command' directive, generate the link target with a lower-case name even if the command name is not all lower-case. This is needed to make cross-references to the command definition work since the 'cmake:command' role is marked with the 'lowercase' property.
