external/CMakeLists.txt unconditionally ran FetchContent for GoogleTest during CMake configure, regardless of DLAF_BUILD_TESTING. Wrap the fetch in if(DLAF_BUILD_TESTING) so library-only configures (-DDLAF_BUILD_TESTING=OFF) don't clone and configure GoogleTest for nothing. Closes eth-cscs#26.

Closes #26.
external/CMakeLists.txtwas unconditionally runningFetchContent_Declare/FetchContent_MakeAvailablefor GoogleTest during CMake configure, regardless of whether tests were going to be built. This meant every configure (including-DDLAF_BUILD_TESTING=OFFbuilds, e.g. library-only installs) cloned GoogleTest from GitHub and configured it, even though nothing would ever use it.Change: wrap the GoogleTest
FetchContentblock inif(DLAF_BUILD_TESTING) ... endif(), matching the existing option already used to gateadd_subdirectory(test)in the top-levelCMakeLists.txt.Verified locally (isolated CMake harness, since I don't have the full DLAF dependency stack available):
-DDLAF_BUILD_TESTING=OFF: configure completes, no_deps/googletest-*directories are created.-DDLAF_BUILD_TESTING=ON: configure completes and GoogleTest is fetched/configured exactly as before (_deps/googletest-src,-build,-subbuildall present).
