Subject: [PATCH 1/5] fix(cmake): install DeePMD config for C library builds

Installing DeePMD-kit from a precompiled C library skipped the CMake package config generation, so LAMMPS built-in mode could not resolve find_package(DeePMD).

Generate DeePMDConfig.cmake and DeePMDTargets.cmake for DEEPMD_C_ROOT builds, and include the same package metadata in the packaged libdeepmd_c tarball.

Cover the downstream CMake scenario from issue #5035 by configuring a minimal consumer with find_package(DeePMD REQUIRED CONFIG) against the install prefix and linking DeePMD::deepmd_c.

Subject: [PATCH 5/5] fix(cmake): make imported target config idempotent

Guard the hand-written DeePMD::deepmd_c imported target templates so repeated find_package(DeePMD) calls in the same configure step do not attempt to redefine the target.

Also quote path expansions in the C library build test script.
