To answer myself:
I just saw that you already set CMAKE_INSTALL_PREFIX, so ignore that
part of my answer. Unfortunately, as far as I am aware it is not
possible to split building with ExternalProject_Add into separate build
and install steps, so your options essentially boil down to:
1) Give yourself write permissions for ${OUTPUT_PATH} and run the build.
You should then probably remove write access for ${OUTPUT_PATH} again
once you are done.
2) Run the entire build as root.
Since you should be doing as little as possible as root, I would
strongly suggest option 1.

Hi Steven,
I would assume the problem is that you do not have write permissions
for /usr/lib. You either need to give yourself the appropriate rights,
our run the build as root (which is probably a very bad idea). If you
don't want to actually install to /usr/lib, you can pass a different
CMAKE_INSTALL_PREFIX to the build via ExternalProject_Add's CMAKE_ARGS
argument, i.e. something like
ExternalProject_Add(xxx
...
CMAKE_ARGS -DCMAKE_INSTALL_PREFIX=<where to install LLVM to>

Hi everyone,
i'm trying to compile llvm with ExternalProject_Add and get the
following error:

I followed the instructions from llvm.org but i still get this error
during installation (the build process works fine but during install i
get this error).
best regards!
