# It's important to realize that CMake implicitly concatenates

|
# CMAKE_CXX_FLAGS with (e.g.) CMAKE_CXX_FLAGS_RELEASE for Release builds. So
|
|
# set switches in CMAKE_CXX_FLAGS that should affect all builds, but in
|
|
# CMAKE_CXX_FLAGS_RELEASE or CMAKE_CXX_FLAGS_RELWITHDEBINFO for switches
|
|
# that should affect only that build variant.
|
|
#
|

# Also realize that CMAKE_CXX_FLAGS may already be partially populated on
|
|
# entry to this file.
