TokuDB tries to build on OS X, even when disabled in compile flag

I compile MariaDB from a shell script that I have written that runs CMake from the command line. I do not use a repository like Homebrew. When compiling 10.1.8 on my OS X 10.11 MacBook Pro, I ran into a couple of issues. The first was easy to sort out and involved patching a CMakesList.txt file so mroonga will compile with clang.

The other issue was a bit more perplexing. I disable TokuDB in my builds with “-DWITHOUT_TOKUDB_STORAGE_ENGINE=ON”. This does not work 10.1.8 and my builds kept failing during make when the script tried to build TokuDB. I also tried using “-DWITH_TOKUDB_STORAGE_ENGINE=OFF” and “-DWITHOUT_TOKUDB=1” in my script, but make still wanted to build TokuDB. Interestingly, if I used the CMake GUI and un-ticked TokuDB, make was successful.

Eventually, I compared the CMakeList.txt for TokuDB in 10.1.8 to the one in 10.0.21. I replaced this section from the 10.1.8 TokuDB CMakeList.txt file…

IF(NOT TOKUDB_OK OR PLUGIN_TOKUDB STREQUAL "NO")

  RETURN()

ENDIF()

with this from the 10.0.21 TokuDB CMakeList.txt file:

IF(NOT TOKUDB_OK OR WITHOUT_TOKUDB OR WITHOUT_TOKUDB_STORAGE_ENGINE)

  RETURN()

ENDIF()

Now my code builds without TokuDB.

It looks like the 10.1.8 change to the TokuDB CMakeList.txt broke the ability to compile on OS X. Or has the syntax changed for disabling TokuDB?
