Fix version variable in reference manual PDF filename

[cottsay]

🦟 Bug fix

Summary

The variable SDF_VERSION_FULL is a C preprocessor macro which is set to the value of the CMake variable PROJECT_VERSION_FULL in config.hh.in. It is not defined as a CMake variable itself, and currently evaluates to an empty string resulting in refman.pdf being renamed to sdf-.pdf.

sdformat/include/sdf/config.hh.in

Line 43 in e7d7cef

#define SDF_VERSION_FULL "${PROJECT_VERSION_FULL}"

$ grep SDF_VERSION_FULL . -R
./src/gz.cc:  return _strdup(SDF_VERSION_FULL);
./src/gz.cc:  return strdup(SDF_VERSION_FULL);
./src/gz_TEST.cc:  return " --force-version " + std::string(SDF_VERSION_FULL);
./doc/CMakeLists.txt:    ${CMAKE_BINARY_DIR}/doxygen/latex/sdf-${SDF_VERSION_FULL}.pdf
./include/sdf/config.hh.in:#define SDF_VERSION_FULL "${PROJECT_VERSION_FULL}"

We don't actually use the generated pdfs for anything AFAIK. I'll create an issue to remove them.

EDIT: #1364
