Description
The standard Ubuntu LTS 18 distribution is missing xxHash. The root build fails. I have installed golang-github-cespare-xxhash-dev, but that does not solve the problem. This is a vaguely familiar problem.
-- Looking for xxHash CMake Error at /home/vagrant/build/e19/build/cmake/v3_18_2/Linux64bit+4.15-2.27/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:165 (message): Could NOT find xxHash (missing: xxHash_LIBRARY xxHash_INCLUDE_DIR) Call Stack (most recent call first): /home/vagrant/build/e19/build/cmake/v3_18_2/Linux64bit+4.15-2.27/share/cmake-3.18/Modules/FindPackageHandleStandardArgs.cmake:458 (_FPHSA_FAILURE_MESSAGE) cmake/modules/FindxxHash.cmake:50 (find_package_handle_standard_args) cmake/modules/SearchInstalledSoftware.cmake:16 (_find_package) cmake/modules/SearchInstalledSoftware.cmake:261 (find_package) CMakeLists.txt:192 (include)

The solution is to enable the builtin xxhash.

We had this in root v6_20_08a
elif [ `lsb_release -d | cut -f2 | cut -f1 -d" "` = "Ubuntu" ]; then
