Incorect TBB test in cmake scripts

[yurivict]

CMake Error at /usr/local/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
  Could NOT find TBB (missing: Tbb_LIB_COMPONENTS tbbmalloc_proxy) (found
  suitable version "2019.0", minimum required is "2017.0")

also having this issue with 2018.0

EDIT: i solved this by just removing tbbmalloc_proxy from the _TBB_COMPONENT_LIST in build/FindTBB.cmake.

I have a feeling that this may be related to the fact that tbbmalloc_proxy isn't actually a library, just an include file, so for example in line 238 of FindTBB.cmake

foreach(COMPONENT ${TBB_FIND_COMPONENTS})
  find_library(Tbb_${COMPONENT}_LIBRARY ${COMPONENT}
    ${_FIND_TBB_ADDITIONAL_OPTIONS}
    PATHS ${_TBB_LIBRARYDIR_SEARCH_DIRS}
    PATH_SUFFIXES ${TBB_PATH_SUFFIXES}
  )

seems like it would fail if COMPONENT is tbbmalloc_proxy.

I could be completely wrong, but I did just successfully build it.

@yurivict / @aflecken what platforms are you running into this issue on, are you both on FreeBSD?
