I didn't get around to writing a reproducer, but I did send an extensive
complaint to the CMake user group. I haven't heard anything back yet. I finally
got this to work by adding this to the CMakeLists.txt file
if (NOT BUILD_SHARED_LIBS)
target_link_libraries(gridpack_math

It would be good to report a reduced test case upstream. They may not fix it,
but a lot of things related to static libraries don't work without coaxing and
they'll never get fixed if people who use CMake with static libraries don't
make their voices heard.

Argh, I'm an idiot. I can't write a proper print statement in CMake.
The PETSC_STATIC_LDFLAGS variable is showing all the libraries so probably all
I need to do is substitute that for PETSC_LDFLAGS in the GridPACK CMake build
(once I find it) when the build is static.

You can run 'pkg-config --static --libs
PETSC_DIR/PETSC_ARCH/lib/pkgconfig/petsc.pc' to verify if pkg-config is able to
obtain 'Libs.private' values.
And then you would need help from someone who can debug cmake - on why
PETSC_STATIC set by cmake does not reflect this value [as it should - per
The static versions of the variables exist (PETSC_STATIC), but they appear to
have the same values as the non-static variables.
As I mentioned, I'm a complete novice at pkgconfig, but it looks like if you
could add the contents of Libs.private to the link line, you'd be in business.
Any idea

I don't know how this info gets propagated up the build chain.

The relevant pkg-config commands are:
balay@sb /home/balay/petsc (release=)
$ pkg-config --libs arch-linux-c-debug/lib/pkgconfig/petsc.pc
-L/home/balay/petsc/arch-linux-c-debug/lib -lpetsc
balay@sb /home/balay/petsc (release=)
$ pkg-config --shared --libs
Bruce,
Can you please send the PkgConfig calls that you make to get the PETSc
values? And then exactly what PETSc PkgConfig returns.
Thanks

Perhaps the easy fix is to build PETSc as shared libraries. [this is the
default anyway]
However wrt pkgconfig:
$ cat arch-linux-c-debug/lib/pkgconfig/petsc.pc
prefix=/home/balay/petsc/arch-linux-c-debug
exec_prefix=${prefix}
includedir=${prefix}/include
libdir=${prefix}/lib
Hi,
We recently switched the CMake configuration on our GridPACK application to use
the PkgConfig utility instead of Jeb Brown’s FindPETSc.cmake module. This seems
to work on a number of platforms but it is failing to link on others. It
appears that the build cannot find the LAPACK and BLAS
