The centos7 on rhel8 was not running the install tests
as the path to cmake/ctest wasn't valid. This causes
the causes the following issues:
1. NOT_RUN tests with REPEAT don't show up in CMake failed
output fixed by:
https://gitlab.kitware.com/cmake/cmake/-/merge_requests/4801
2. failed tests cause ctest_test to return an error code,
which propagates to the script, which propagates to
having ctest running the script return an error.
