Sorry about the incorrect fix, I will build with -Wmissing-include-dirs from 
now on. However I wonder how to fix the original problem.

Would it be legal to remove MYSQL_INCLUDE_DIR entirely and just rely on 
MYSQL_CFLAGS to specify -I/path/to/mysql ?

E.g. is cmake's include_directories(/dir) just a syntactic sugar for 
add_definitions(-I/dir) or it would break build on non-gcc platforms? I'd 
rather avoid filtering "-I" out of MYSQL_INCLUDE_DIR in CMakeLists.
