OS: ArchLinux x86_64

When building with following config:

mkdir -p "build"
cd "build"
LDFLAGS+="-Wl,--no-undefined" \
cmake -DCMAKE_BUILD_TYPE:STRING=Release \
      -DCMAKE_INSTALL_LIBDIR:PATH=lib \
      -DCMAKE_INSTALL_PREFIX:PATH=/usr \
      -DBUILD_TESTS=1 \
      -DCPPUNIT_FOUND=1 \
      -DCPPUNIT_INCLUDE_DIRS=/usr/include \
      -DCPPUNIT_LIBRARIES=/usr/lib/libcppunit.so \
      -DXRD_PYTHON_REQ_VERSION=3.7 \
      ../
