+Subject: [PATCH] Fix exported OpenBLASTargets.cmake
+
+When both BUILD_SHARED_LIBS and BUILD_STATIC_LIBS are enabled,
+cmake export both of them to OpenBLASTargets under tha same name `OpenBLAS::OpenBLAS`
+which leads to fatal error about OpenBLAS::OpenBLAS being both static and shared target.
+This change makes cmake export only the shared library in that case.
+There is another solution to treat them as components,
+but I am afraid that will make it backward incompatible.
