Are these the literal outputs or did you edit them? Please don't. There should be no "$" in those outputs. What I get:
```
LLVM_TREE_AVAILABLE: OFF
toolchain_lib_subdir: lib/x86_64-unknown-linux-gnu
FLANG_RT_OUTPUT_RESOURCE_DIR: /home/meinersbur/build/llvm-project-flangrt/release_runtimes/runtimes/flang-rt
FLANG_RT_INSTALL_RESOURCE_PATH: lib/clang/21
FLANG_RT_OUTPUT_RESOURCE_LIB_DIR: /home/meinersbur/build/llvm-project-flangrt/release_runtimes/runtimes/flang-rt/lib
FLANG_RT_INSTALL_RESOURCE_LIB_PATH: lib/clang/21/lib/x86_64-unknown-linux-gnu
...

```
If I use `-DCMAKE_INSTALL_PREFIX="\\\$PREFIX"` I do get different output (that does not work).
