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 FindPkgConfig doc] [sorry - I don't understand cmake - or how one would debug cmake issues] Satish On Tue, 22 Feb 2022, Palmer, Bruce J via petsc-users wrote: > 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.
