LLVM (script located at ~/build/llvm/release_nopolly_dylib.sh):

  #! /usr/bin/env bash
  set -e
  
  TYPENAME=`basename $0 .sh`
  BUILDPATH=`realpath --no-symlinks $(dirname $0)`
  PROJECTNAME=`basename ${BUILDPATH}`
  TYPEPATH="${BUILDPATH}/${TYPENAME}"
  SRCPATH=~/src/${PROJECTNAME}
  
  mkdir -p "${TYPEPATH}"
  cd "${TYPEPATH}"
  
  cmake "${SRCPATH}" -GNinja          \
  -DLLVM_BUILD_LLVM_DYLIB=ON          \
  -DLLVM_LINK_LLVM_DYLIB=ON           \

Polly:

  #! /usr/bin/env bash
  set -e
  
  TYPENAME=`basename $0 .sh`
  BUILDPATH=`realpath --no-symlinks $(dirname $0)`
  PROJECTNAME=`basename ${BUILDPATH}`
  TYPEPATH="${BUILDPATH}/${TYPENAME}"
  SRCPATH=~/src/llvm/tools/${PROJECTNAME}
  
  mkdir -p "${TYPEPATH}"
  cd "${TYPEPATH}"
  
  cmake "${SRCPATH}" -GNinja          \
  -DLLVM_INSTALL_ROOT=${HOME}/build/llvm/release_nopolly_dylib \
  -DCMAKE_PREFIX_PATH=${HOME}/build/llvm/release_nopolly_dylib \
  -DCMAKE_BUILD_TYPE=Release          \
  -DCMAKE_INSTALL_PREFIX=${HOME}/install/${PROJECTNAME}/${TYPENAME} \
  -DCMAKE_EXPORT_COMPILE_COMMANDS=ON  \
  -DLLVM_ENABLE_ASSERTIONS=ON         \
  -DPOLLY_ENABLE_GPGPU_CODEGEN=ON

This automatically finds `FileCheck` in the build dir, which is nice, but fails with the aforementioned error.

`-DLLVM_DIR=-DLLVM_DIR=${HOME}/build/llvm/release_nopolly_dylib` doesn't work.
