Subject: [PATCH] Fix CMake install step: add install targets and preserve
 RPATH

- Add install(TARGETS ...) for main_dca, main_analysis, chi_q_omega,
  and cluster_solver_check application binaries
- Set CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE so installed binaries
  can find shared libraries (OpenBLAS, HDF5, FFTW) without
  LD_LIBRARY_PATH at runtime

Tested with Ninja generator + spack environment.
