Great, I already did the git pull here.

I just tried to compile it here using your script as baseline:
$ cmake -G Ninja -DRT_SUPPORT_SANITIZERS=ON
Then I tried to compile this example:
$ ~/dlang/ldc/build/bin/ldc2 test.d
And get the same error:
Error: cannot find source code for runtime library file 'object.d'
ldc2 might not be correctly installed.
Please check your ldc2.conf configuration file.
Installation instructions can be found at
Specify path to file 'object.d' with -I switch
I'm not trying my code yet, this is just the master branch that
I'm trying to use.
Any ideas or should I report this as a issue?

I will test it as soon as I can compile LDC without my code!
