[petsc-users] Doubt about distribution of PETSc in a CMake project

[Sebastian Gutierrez]

Hello Satish,

First of all, I want to thank you for your response. I have been trying to
perform the second alternative you suggested, but I am having problem while
I am executing the cmake command. Could you help me with it? I got this
error in the image attached, additionally I config petsc with this
configuration: *./configure --with-cc=gcc --with-cxx=g++ --with-fc=gfortran
--with-debugging=0 COPTFLAGS='-O3 -march=native -mtune=native'
CXXOPTFLAGS='-O3 -march=native -mtune=native' FOPTFLAGS='-O3 -march=native
-mtune=native' --with-shared-libraries=0 --download-mpich*
And this cmake command: *cmake -DPETSC_DIR=/usr/lib/petsc-3.17.2
-DPETSC_ARCH=arch-linux-c-opt all -DPETSC_CURRENT=ON ../*

I hope you can help me, please.

Best regards,

Sebastian
