Resolve "tqroot fails to load library in plain CAFCore setup"

Release notes

Fixed library paths not being properly exported in ASG setups where CAFCore has no parent package (usually: CAFCore-only setup)

Details

ASG cmake magic was not executed before constructing the paths to the compiled libraries, hence, these paths were incomplete and, e.g., tqroot could not load the library.

Closes #157 (closed)
