triSYCL Update, master branch (2021.04.26.)
Updated the version of triSYCL to build. Updating the build setup along the way, allowing the triSYCL build to find the range-v3 headers from an LCG release.
The update is necessary to address the build issue in x86_64-centos7-clang10-opt
nightlies, as described in ATLINFR-4001. (I checked, with the new version the build of AthExSYCL does succeed in an x86_64-centos7-clang10-opt
build...)
