Motivation and Context

This PR resolves library dependency issues in the dEdx fitter calibration module and removes an unnecessary OpenMP compilation flag. The changes allow cleanup of build configuration introduced in PR #4139, which added the -fopenmp flag due to perceived OpenMP dependencies that do not actually exist in the code.

Key Changes

• Makefile.am: Replaced -ltrack_reco with -ltrackbase_historic in the libdedxfitter_la_LIBADD linkage. The module already includes headers from trackbase_historic (specifically SvtxTrackMap.h and TrackAnalysisUtils.h) and was already linking against libtrackbase_historic and libtrackbase_historic_io.
• configure.ac: Removed the -fopenmp compilation flag from CXXFLAGS, eliminating an unnecessary OpenMP dependency that was not actually used in the code.

Risk Assessment

• Low Risk: The code contains no OpenMP pragmas (#pragma omp) or OpenMP API calls, confirming the flag was unnecessary.
• No Behavioral Impact: The dEdx fitting algorithms (contained in GlobaldEdxFitter and dEdxFitter) rely on ROOT mathematical minimization and track analysis utilities from trackbase_historic, not on parallelization.
• Transitive Dependencies: The libtrack_reco library dependency appears to have been redundant, as the required functionality is already available through the direct libtrackbase_historic dependency.
• Build Simplification: Removes outdated/incorrect build configuration without affecting runtime behavior.

Possible Future Improvements

• Review and update the comment in configure.ac that claims "this package needs openmp," which appears to be outdated documentation.
• Consider verifying across the codebase whether other modules with similar comment patterns have the same unnecessary OpenMP dependencies.

Note: AI-assisted analysis has been used in identifying these patterns. Manual verification of transitive dependencies and actual library requirements is recommended.
