================
Comment at: openmp/runtime/src/CMakeLists.txt:361
     install(CODE "execute_process(COMMAND \"\${CMAKE_COMMAND}\" -E copy \"${LIBOMP_LIB_FILE}\"
-      \"${alias}${LIBOMP_LIBRARY_SUFFIX}\" WORKING_DIRECTORY \"\${CMAKE_INSTALL_PREFIX}/bin\")")
+      \"${alias}${LIBOMP_LIBRARY_SUFFIX}\" WORKING_DIRECTORY \"\${CMAKE_INSTALL_BINDIR}\")")
     install(CODE "execute_process(COMMAND \"\${CMAKE_COMMAND}\" -E copy \"${LIBOMP_IMP_LIB_FILE}\"
----------------
This change seems to have broken one aspect: When doing `ninja install` I now get a warning saying `Error copying file "libomp.dll" to "libiomp5md.dll".`, and `libiomp5md.dll` isn't installed.

I believe the reason is that the inline cmake snippet is written to `runtime/src/cmake_install.cmake` and then executed on install, but on install, `${CMAKE_INSTALL_BINDIR}` isn't set (as `GNUInstallDirs` isn't included there). Should this maybe expand `${CMAKE_INSTALL_BINDIR}` right here instead of deferring it to the install cmake, or what's the right course of action?
