I use a script like the one shown below.

I assume you are installing your warez into $HOME. You would use
--prefix=$HOME when configuring. So binaries are in $HOME/bin,
libraries are in $HOME/lib, etc.

Use -fdebug-prefix-map as an option to CFLAGS and CXXFLAGS like so:

    -fdebug-prefix-map=${PWD}="${HOME}/src/gpu-simulator"

Then, after configure, make and make install, execute the script:

    # run from the gpu-simulator directory, where you configure
    bash copy-sources.sh "${PWD}" "${HOME}/src/gpu-simulator"

Here's the copy-sources.sh script:

$ cat copy-sources.sh
#!/usr/bin/env bash

src_dir="$1"
dest_dir="$2"

if [[ -z "${src_dir}" ]]; then
    echo "Please specify a source directory"
    exit 1
fi

if [[ ! -d "${src_dir}" ]]; then
    echo "Source directory is not valid"
    exit 1
fi

if [[ -z "${dest_dir}" ]]; then
    echo "Please specify a destination directory"
    exit 1
fi

cd "${src_dir}" || exit 1
rm -rf "${dest_dir}"
mkdir -p "${dest_dir}"

IFS= find "./" \( -name '*.h' -o -name '*.hpp' -o -name '*.hxx' -o \
                  -name '*.c' -o -name '*.cc' -o \
                  -name '*.cpp' -o -name '*.cxx' -o -name '*.CC' -o \
                  -name '*.s' -o -name '*.S' \) -print | while read -r file
do
    # This trims the leading "./" in "./foo.c".
    file=$(echo -n "${file}" | tr -s '/' | cut -c 3-);
    cp --parents --preserve=timestamps "${file}" "${dest_dir}"
done

exit 0
