Doing this seems to help:

diff --git a/CMakeLists.txt b/CMakeLists.txt
index 85d4b51..9615a3c 100644
--- a/CMakeLists.txt
+++ b/CMakeLists.txt
@@ -765,9 +765,9 @@ add_subdirectory(utils/TableGen)
 # an entire module might include header, which depends on intrinsics_gen. This
 # should be right after LLVMSupport and LLVMTableGen otherwise we introduce a
 # circular dependence.
-if (LLVM_ENABLE_MODULES)
+#if (LLVM_ENABLE_MODULES)
   list(APPEND LLVM_COMMON_DEPENDS intrinsics_gen)
-endif(LLVM_ENABLE_MODULES)
+#endif(LLVM_ENABLE_MODULES)
 
 add_subdirectory(include/llvm)
 
but that does not seem like a real solution.
