unfortunately I am having trouble when I try to build “preCICE using CMake”

  build]$ cmake -DBUILD_SHARED_LIBS=ON ..
.....-- Validating Prettyprint - success
CMake Error at /usr/share/cmake/Modules/FindPackageHandleStandardArgs.cmake:164 (message):

I installed PETSc version “3.13.0” from source ,

PETSC_DIR                        /home/guido/petsc/petsc

install according PETSc: Documentation: Installation

./configure
make all test

 Configure stage complete. Now build PETSc libraries with:
   make PETSC_DIR=/home/guido/petsc/petsc PETSC_ARCH=arch-linux-c-debug all

When compiling PETSc you should choose a prefix (installation directory). Then, after compilation PETSc prints a command for installation (something like make PETSC_DIR=.... Did you run this command?

If you do not run this command, you will have incomplete headers, for example, as the files are all copied to the correct location during the install step. Your include/ dir seems to lack the C headers and more. My include/ of PETSc looks like this for example

index.html                  petscdmdatypes.h.html    petscdrawtypes.h       petscmatelemental.h       petsctao.h.html
makefile                    petscdmfield.h           petscdrawtypes.h.html  petscmatelemental.h.html  petsctaolinesearch.h
makefile.html               petscdmfield.h.html      petscds.h              petscmath.h               petsctaolinesearch.h.html
petsc                       petscdmforest.h          petscds.h.html         petscmath.h.html          petsctime.h

@gas The PETSc website now states that one should use the generated pkg-config file to detect PETSc from CMake. I developed a wrapper which is backward compatible with the previous use of PETSc and should resolve most of the PETSc-related issues.
