Looks like Philip suggested a patch from the bug tracker. Did you try it
out?

I believe the value of CMAKE_CXX_FLAGS* is read each time you add a
target. So use something like this:

set (CMAKE_CXX_FLAGS_DEBUG_ORIG ${CMAKE_CXX_FLAGS_DEBUG})
set (CMAKE_CXX_FLAGS_DEBUG "myflag1")
add_library(mylib1 ...)
set (CMAKE_CXX_FLAGS_DEBUG "myflag2")
add_library(mylib2 ...)
set (CMAKE_CXX_FLAGS_DEBUG ${CMAKE_CXX_FLAGS_DEBUG_ORIG})
