Hi Peter,
Surprisingly I fixed it. In 3 easy steps :) I don't even know if all
cores are used, but it does compile and start.
*Cherry-pick your 4 commits, fix conflicts*
0e19e394243f Omp variable int and omp.h includes
82a46f59a410 Replace reduction by critical
3fc94be7814c Add openmp dependency to AlgotihmsExt and MapperExt
75840ab56a34 Add openmp as external project
*Modify **MITK_OpenMP_Config.cmake**to look like
*
find_package(OpenMP REQUIRED)
if(OpenMP_CXX_FOUND)
list(APPEND ALL_LIBRARIES ${OpenMP_CXX_LIBRARIES})
endif()
*Fix Classificaton/CLUtilities dependencies* and other simple ***clang *
compilation errors
*Add "OpenMP|OpenMP_CXX".
*** We don't even use OpemMP there, but we use Eigen which uses OpenMP.
I'm not sure what's the clean way to handle this. I just know that it
fixes the problem.
My setup is:
* macOS 10.13.6, XCode 10.0, Qt 5.11.1
* brew install libomp cmake
* cmake -DCMAKE_BUILD_TYPE:STRING=Release -DBUILD_TESTING:BOOL=OFF
-DMITK_BUILD_ALL_PLUGINS:BOOL=ON -DMITK_USE_Vigra:BOOL=ON
-DMITK_USE_MatchPoint:BOOL=ON -DGIT_EXECUTABLE:PATH=/usr/bin/git ..
I will test "port install libomp" and/or "libomp-devel" in the next days
because I'm not really a homebrew user. I'll keep you updated.

This is where I'm stuck. Didn't have the time to investigate further
since I'm out of office for a while.

Hi Peter,
What do you mean by "unsuccessful until now"? I tested
T25191-v2018.04-beta, cherry-picking your 4 OpenMP commits and it's
still unsuccessful. I have a list of undefined symbols, for example
Undefined symbols for architecture x86_64:
"___kmpc_critical", referenced from:
_.omp_outlined..8 in mitkWeightedPointTransform.cpp
Is this where you're stuck at? Or were you successful?

fix this following this solution:
