From 89ab78e360b7b20ebe1bc89736880a8e4aaa9e6e Mon Sep 17 00:00:00 2001

Subject: [PATCH] [cmake] Make libgomp & libiomp5 alias install optional
Introduce a new LIBOMP_INSTALL_VARIABLES cache variable that can be used
to disable creating libgomp and libiomp5 aliases on 'make install'.
Those aliases are undesired e.g. on Gentoo systems where libomp is used
purely by clang.
