Conversion script in AddTest.cmake with usage.

Write the <test_def>...</test_def> into x.xml,
run the script:

cmake . |& \
    awk 'BEGIN{x=0}/###BEGIN###/{f=$2;x=f".xml";print x;print "" > x;next}/###END###/{x=0;next}{if (x != 0) print $0 > x}' | \
    parallel -j1 \
        'xmlstarlet ed -a "//OpenGeoSysProject/linear_solvers" -t elem -n test_definition -v "$(xmlstarlet sel -t -c //test_definition/\* {})" {.} | \
         xmlstarlet unesc | \
         xmlstarlet format -s 4 > {.}.tmp \
         && mv {.}.tmp {.}; \
         rm {}'
