Compile for OSX (requires libomp)

[damian0815]

Support for building on OSX.

Wrangle: needs a libomp.dylib. Xcode ships with clang that supports OpenMP (-Xpreprocessor -fopenmp) but you still need to manually build libomp.dylib and place it somewhere in search paths. Ref https://stackoverflow.com/a/47230419/42961 . To build libomp and install headers and libs in /usr/local, do this:

$ cd /tmp
$ svn co http://llvm.org/svn/llvm-project/openmp/trunk libomp
$ cd libomp
$ mkdir build && cd build
$ cmake -DCMAKE_INSTALL_PREFIX=/usr/local ..
$ make && make install

Got the following compile error on Cmake. Could any genius here please help? ; )

My build stop as follows, though I have build libomp and install headers and libs in /usr/local.

You are in 'detached HEAD' state. You can look around, make experimental changes and commit them, and you can discard any commits you make in this state without impacting any branches by performing another checkout.

If you want to create a new branch to retain commits you create, you may do so (now or later) by using -b with the checkout command again. Example:

git checkout -b

It seems that your internet connection failed. So git could not download the external projects.
