Also, the following files should be checked:

* src/lib_misc.c
* src/lj_memprof.c
* src/lj_memprof.h
* src/lj_sysprof.h
* src/lj_utils.h
* src/lj_wbuf.h

* test/PUC-Rio-Lua-5.1-tests/libs/CMakeLists.txt
* test/lua-Harness-tests/CMakeLists.txt

The output is splitted (thanks CMake). I found the only way to join
lines via `string(CONCAT WARN_MSG <str1> <str2>)`.

The ${MSG} is undefined, so this line does nothing and can be deleted.

Should it be mmapped instead (like map -> mapped)?
