No, the test infrastructure should not need modification for this.
Under IDE generators the generator expression will be evaluated
once for every configuration.  Perhaps RunCMake isn't the best
category of tests after all.

Instead update Tests/GeneratorExpression to do

 -Dtest_config_debug=$<CONFIG:Debug>$<CONFIG:DEBUG>$<CONFIG:DeBuG>
 -Dtest_config_release=$<CONFIG:Release>$<CONFIG:RELEASE>$<CONFIG:ReLeAsE>
 ...other two configs...

Then in check.cmake verify that each variable is set to all 0s
or all 1s.
