I like the change but there are two more places that need to be updated:

• the python path where the module is looking for the shared library
• the post-install tests in test/post_install_test.cmake.sh lines 22 and 29

This should pass the CI now.

Done. I changed it from CMAKE_INSTALL_* to CMAKE_INSTALL_FULL_* in some places to force it to be an absolute path.

Hmm, test fails as lib is hardcoded here:

but heffte now gets installed in lib64.

Good catch. I will update the spack package to put it back in lib. I think all xSDK packages used to default to lib as a requirement (don't know if it's still a valid one).

We can merge this one meanwhile, this is only relevant towards @develop builds.

I did a git grep through all the package.py and the majority have lib64 hard-coded, but some still have lib.
