## Using a custom version of hwloc
```
git clone https://github.com/open-mpi/hwloc ../hwloc
cd ../hwloc
sh autogen.sh
sh configure --disable-picky --disable-cairo --disable-cpuid --disable-libxml2 --disable-io --disable-pci --disable-opencl --disable-cuda --disable-nvml --disable-gl --disable-libudev --disable-netloc
make -C hwloc
cd ../hhwloc
stack exec -- hsc2hs src/System/Libhwloc/Internal -I../hwloc/include
stack ghci --ghci-options="-L../hwloc/hwloc/.libs -lhwloc"
```
