CMake Keywords

Important

All CMake keywords are prefixed with PRESSIO_ which is case-sensitive.

Recall that to set a keyword in CMake you used the syntax -Dkeyword_name.

Third-party Libraries (TPLs)

The following options control enabling TPLs:

Variable	Description	Default
PRESSIO_ENABLE_TPL_EIGEN	self-explanatory	ON
PRESSIO_ENABLE_TPL_TRILINOS	self-explanatory	OFF
PRESSIO_ENABLE_TPL_MPI	self-explanatory	OFF automatically ON if PRESSIO_ENABLE_TPL_TRILINOS=ON
PRESSIO_ENABLE_TPL_KOKKOS	self-explanatory	OFF; automatically ON if PRESSIO_ENABLE_TPL_TRILINOS=ON
PRESSIO_ENABLE_TEUCHOS_TIMERS	self-explanatory	OFF automatically ON if PRESSIO_ENABLE_TPL_TRILINOS=ON
PRESSIO_ENABLE_TPL_BLAS	self-explanatory	OFF; automatically ON if PRESSIO_ENABLE_TPL_LAPACK=ON or PRESSIO_ENABLE_TPL_TRILINOS=ON
PRESSIO_ENABLE_TPL_LAPACK	self-explanatory	OFF; automatically ON if PRESSIO_ENABLE_TPL_BLAS=ON or PRESSIO_ENABLE_TPL_TRILINOS=ON

Obviously, the choice of which TPLs to enable is related to your application’s dependency requirements. For example, if you have an application that relies on Trilinos data structures and want to use pressio, then it makes sense to enable the Trilinos dependency. On the contrary, if you have an application that relies only on Eigen data structures, then it makes sense to only leave only Eigen on and disable the rest.

Also, we note that some of the cmake variables listed above are connected and cannot be turned on individualy. For example, if we enable Trilinos then pressio automatically enables also Kokkos, BLAS, LAPACK and MPI.

Other Options

Variable	Description	Default
PRESSIO_ENABLE_DEBUG_PRINT	to enable debugging print statements	OFF
PRESSIO_ENABLE_CXX17	enables C++17 standard	ON since min standard is 17
PRESSIO_ENABLE_CXX20	enables C++20 standard	OFF; turned on if CMAKE_CXX_STANDARD is set to 20
