From b03139b1d210865526ab0e945aa79b2627f8c202 Mon Sep 17 00:00:00 2001 From: Lasse Collin Date: Fri, 15 Mar 2024 17:15:50 +0200 Subject: [PATCH] Build: Use only the generic symbol versioning with NVIDIA HPC Compiler. This does the previous commit with CMake. AC_EGREP_CPP uses AC_REQUIRE so the outermost if-commands must be changed to AS_IF to ensure that things wont break some day. See 5a5bd7f871818029d5ccbe189f087f591258c294.
