In GNU Make you probably should do this with $(addprefix include/, $(HEADER))

set(SRC hello.cpp bla.cpp blu.cpp)

string(REGEX REPLACE "\\.cpp(;|$)" ".h\\1" HEADER "${SRC}")
string(REGEX REPLACE "([^;]+)(;|$)" "include/\\1\\2" HEADER_WITH_DIR "${HEADER}")

message("HEADER = ${HEADER}")
message("HEADER_WITH_DIR = ${HEADER_WITH_DIR}")
