cmake/jemalloc.cmake:
  for dependencies to work, LIBJEMALLOC should be the target name, not the path
storage/tokudb/CMakeLists.txt:
  * check the preconditions
  * disable bdb tests (compilation errors)
  * set variable, instead of SET_PROPERTY. same effect,
    but doesn't fail when a plugin is disabled (that is, a target does not exist)
storage/tokudb/ft-index/CMakeLists.txt:
  cmake should not look into examples/ directory,
  there is hand-crafted examples/Makefile that
  cmake will overwrite
storage/tokudb/ft-index/buildheader/CMakeLists.txt:
  the syntax is ADD_EXECUTABLE(target source) and "source" is the file name
storage/tokudb/ft-index/cmake_modules/TokuMergeLibs.cmake:
  Libraries must be specified in the specific order,
  REMOVE_DUPLICATES cannot be used, because it destroys this order.
  
  (when OSLIBS contains "-lpthread -ljemalloc -lpthread", REMOVE_DUPLICATES
  makes it "-lpthread -ljemalloc". But a thread library *must* be *after* jemalloc)
storage/tokudb/ft-index/cmake_modules/TokuSetupCTest.cmake:
  * 'which' might print errors to stderr, they are not important, shut them up
  * we don't have TOKUDB_DATA, no need to warn about it
  * don't configure_file into itself (with input=output)
storage/tokudb/ft-index/cmake_modules/TokuThirdParty.cmake:
  jemalloc is built externally to tokudb/ft-index
