With Meson you don't have to care about the details, just pass `gtest` or `gmock` to `dependency` and it will do everything for you. If you want to use GMock, it is recommended to use GTest as well, as getting it to work standalone is tricky. +## MPI ## + +MPI is supported for C, C++ and Fortran. Because dependencies are +language-specific, you must specify the requested language using the +`language` keyword argument, i.e., + * `dependency('mpi', language='c')` for the C MPI headers and libraries + * `dependency('mpi', language='cpp')` for the C++ MPI headers and libraries + * `dependency('mpi', language='fortran')` for the Fortran MPI headers and libraries + +Meson prefers pkg-config for MPI, but if your MPI implementation does not +provide them, it will search for the standard wrapper executables, `mpic`, +`mpicxx`, `mpic++`, `mpifort`, `mpif90`, `mpif77`. If these are not in your +path, they can be specified by setting the standard environment variables +`MPICC`, `MPICXX`, `MPIFC`, `MPIF90`, or `MPIF77`, during configuration. + ## Qt5 ## Meson has native Qt5 support. Its usage is best demonstrated with an example. |
