The simplest option is to use the helper script make_pdf.sh:
git clone git@github.com:DMSC-Instrument-Data/documents.git
cd documents
./make_pdf.sh
Generated .pdf files can be found in pdf/ (which is actually a symlink to build/pdf/).
Alternatively, you can use a cmake out-of-source build to create .pdf output files:
git clone git@github.com:DMSC-Instrument-Data/documents.git
mkdir build
cd build
cmake ../documents/
make
Generated .pdf files can be found in the folder pdf/.
