cpp tests not run on ci

[epicfarmer]

Description
Only the python tests are run on CI. As a result, the tests are broken.

To Reproduce

• checkout repo
• run cmake -S. -Bbuild -DMINORMINER_BUILD_TESTS=ON
• run cmake --build build

Expected behavior

> cmake --build build

• OS: [Ubuntu 24.10 ]

Additional context
I tried disabing werror in google-test, and tests still failed due to a missing <memory> include.
