We are providing CMake helper files to easily include DBCSR in any other CMake-based project. For this you have to build DBCSR using CMake as described above and then also install it.
As a user being able to run commands as root, use:
sudo cmake --build . -- install # will install to /usr/local
If you can not run commands as root, use -DCMAKE_INSTALL_PREFIX=... when calling CMake to set
an alternative base installation path for DBCSR instead:
cmake -DCMAKE_INSTALL_PREFIX=/my/custom/prefix ..
cmake --build . -- install
In your project's CMake you can then easily search for the DBCSR library:
cmake_minimum_required(VERSION 3.22)
enable_language(Fortran C CXX) # only request the required language
find_package(DBCSR 2.0.0 CONFIG REQUIRED)
find_package(MPI)
# for Fortran:
set(CMAKE_Fortran_FLAGS "-std=f2018") # your Fortran code likely needs to be F2018+ compatible as well
add_executable(dbcsr_example_fortran dbcsr_example.f90)
target_link_libraries(dbcsr_example_fortran DBCSR::dbcsr)
# for C:
add_executable(dbcsr_example_c dbcsr_example.c)
target_link_libraries(dbcsr_example_c DBCSR::dbcsr_c MPI::MPI_C)
# for C++:
add_executable(dbcsr_example_cpp dbcsr_example.cpp)
target_link_libraries(dbcsr_example_cpp DBCSR::dbcsr_c MPI::MPI_CXX)
If you installed DBCSR into a custom prefix, you have to make sure that CMake is able to find the DBCSR CMake configuration:
DBCSR_DIR=/my/custom/prefix cmake ..
