    PrintableOptions.cmake: Correct variable name comparison
    
    CMake 3.20.1 errors out with:
    
    CMake Error at cmake/modules/PrintableOptions.cmake:38 (message):
       variable name cannot be empty
     Call Stack (most recent call first):
       CMakeLists.txt:152 (add_printable_variable)
    
    Change how the parameter value is compared, to fix it.
    
    
    (cherry picked from commit c95a70bfeae25ba11fbe50fe759a6cdb29388e44)
