In install case you can use install(EXPORT ...) command:

   install(TARGETS foo EXPORT FooTargets)
   install(EXPORT FooTargets)

debug will produce: FooTargets.cmake and FooTargets-debug.cmake
release will produce: FooTargets.cmake and FooTargets-release.cmake
Both debug/release versions of FooTargets.cmake are equal.
