Ansible Roles with OS-specific Defaults

This Ansible guide discusses several approaches on how to set different role default variables based / depending on the host operating system aka ansible_distribution / ansible_facts.distribution or other variables. For example, a role variable image_uri should point to the latest cloud image for the host. For CentOS 8 or Red Hat Enterprise Linux (RHEL) 8 the default value should be:

Fix linker errors with VTK-6.0 and MPICH

Suppose you build your C/C++ library using CMake and use find_package(VTK) to include VTK headers and libraries, at Ubuntu Trusty (14.04). You compile and link your code against another MPI implementation like MPICH, e.g. running cmake -DMPI_C_COMPILER=/usr/bin/mpicc.mpich -DMPI_CXX_COMPILER=/usr/bin/mpicxx.mpich ... You setup CMake to compile a C/C++ application and try to link it to your library. The linker will throw an error at one of your library-exported MPI functions, e.g.:

/usr/bin/ld: CMakeFiles/main.cpp.o: undefined reference to symbol 'ompi_mpi_comm_null'
//usr/lib/libmpi.so.1: error adding symbols: DSO missing from command line

VTK 6.0 at Ubuntu Trusty (14.04) is linked against OpenMPI. The CMake files installed in line with VTK (/usr/lib/cmake/vtk-6.0/Modules/vtkParallelMPI.cmake) add the OpenMPI header paths to your library's CMake include directories:

Fix CMake errors of VTK 6.0 with newer GCC revisions

CMake files of VTK 6.0 do not handle newer GCC output correctly and thus fail with:
