In general: yes. In Kconfig this could look like this (copied from one
of our custom .in files):

    choice                                                              
  
        prompt "CMAKE BUILD TYPE"                                       
  
        default ISBUILD_TYPE_EMPTY                                      
  
        help                                                            
  
          This sets CMAKE_BUILD_TYPE for all ifak system libraries and  
          applications. Default is 'RelWithDebInfo' which is the default
          of ptxdist. Possible values are Debug, Release, RelWithDebInfo
          and MinSizeRel.                                               
  
                                                                        
  
    config ISBUILD_TYPE_EMPTY                                           
  
        bool                                                            
  
        prompt "empty"                                                  
  
                                                                        
  
    config ISBUILD_TYPE_DEBUG                                           
  
        bool                                                            
  
        prompt "Debug"                                                  
  
                                                                        
  
    config ISBUILD_TYPE_RELEASE                                         
  
        bool                                                            
  
        prompt "Release"                                                
  
                                                                        
  
    config ISBUILD_TYPE_RELWITHDEBINFO                                  
  
        bool                                                            
  
        prompt "RelWithDebInfo"

        prompt "MinSizeRel"

It's a little more complicated in the .make rule though, you have to
test each bool separatly.
