You can use the <tag> feature on your "exe" (and "lib", if you need it)
rules.  This may be more complicated than you need, though.  :-)

For lib and executable files, it adds "_d" to the end of the base name
("foo_d" on Unix and "foo_d.exe" on Windows) for debug builds and "_sym"
for release builds with debugging symbols.  For libraries, it adds "_st"
if it's a single-threaded build.  It changes the name of the built file,
then all you have to do is do "install name : foo : <location> bin ;"
(note the case of "install").

rule apago_tag ( name : type ? : property-set )  {
   local tags ;
   if [ type.is-subtype $(type) EXE ] || [ type.is-subtype $(type) LIB ]  {
      local v = [ $(property-set).get <variant> ] ;
      local suffix ;
      local extension = [ type.generated-target-suffix $(type) : $(property-set)
 ] ;
      extension = .$(extension) ;
      if $(v) = debug  {
         suffix = _d ;
      } else  {
         if [ $(property-set).get <debug-symbols> ] = "on"  {
            suffix = _sym ;
         }
      }
      if [ type.is-subtype $(type) LIB ] && [ $(property-set).get <threading> ]
= "single"  {
         suffix ?= "" ;
         suffix = $(suffix)_st ;
      }
      if $(suffix) {
         return $(name)$(suffix)$(extension:E="") ;
      }
   }
}
