Mac OS Brew build INSTALL DESTINATION "/usr/local" permissions error

[Create The Imaginable]

When doing a Brew build - https://github.com/vfxpro99/usd-build-club/wiki/USD-on-macOS#building-usd-on-macos-using-brew

I get a /usr/local permissions error, see below...

=== BUILD AGGREGATE TARGET install OF PROJECT usd WITH CONFIGURATION Release ===

Looks like it is related to references to /usr/local in the ~/Projects/stage/build/pxr/cmake_install.cmake file:

if("${CMAKE_INSTALL_COMPONENT}" STREQUAL "Unspecified" OR NOT CMAKE_INSTALL_COMPONENT)
list(APPEND CMAKE_ABSOLUTE_DESTINATION_FILES
"/usr/local/pxrConfig.cmake")
if(CMAKE_WARN_ON_ABSOLUTE_INSTALL_DESTINATION)
message(WARNING "ABSOLUTE path INSTALL DESTINATION : ${CMAKE_ABSOLUTE_DESTINATION_FILES}")
endif()

message(FATAL_ERROR "ABSOLUTE path INSTALL DESTINATION forbidden (by caller): ${CMAKE_ABSOLUTE_DESTINATION_FILES}")
endif()
file(INSTALL DESTINATION "/usr/local" TYPE FILE FILES "~/Projects/stage/build/pxrConfig.cmake")
endif()

I got around this in a pretty questionable way, by chowning /usr/local and suppressing System Integrity Protection. It's probably a good idea to modify the brew build to build to a non /usr/local location. Any thoughts?

In the build-macos-brew.sh I added the line "-DCMAKE_INSTALL_PREFIX=${ROOT}/INSTALL " to cmake and that seems to give me a successful build... See below:

The installed files will show up in stage/INSTALL

cmake -G "Xcode" ../../USD \
-DCMAKE_INSTALL_PREFIX=${ROOT}/INSTALL \
-DOPENSUBDIV_ROOT_DIR=${ROOT}/homebrew \
-DCMAKE_PREFIX_PATH=${ROOT}/homebrew \
...

setting the install prefix is the right approach.
