Using class_maker.py on MantidGeometry breaks the build

[Michael Wedel]

When adding a new class to MantidGeometry with the class_maker.py script, the CMakeLists-file is altered. The following line, which is located near the end of the CMakeLists-file:

   set (SRC_FILES ${SRC_FILES} ${OPENCASCADE_SRC} )

is replaced by an additional line at the beginning of set ( SRC_FILES ...:

   ${SRC_FILES} ${OPENCASCADE_SRC}

which is at the beginning of the file.

After this modification, building Mantid results in the following linker errors (Ubuntu):

../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::OCGeometryHandler(Mantid::Geometry::Object*)'
../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::getTriangleFaces()'
../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::NumberOfTriangles()'
../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::getTriangleVertices()'
../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::NumberOfPoints()'
../bin/libMantidGeometry.so: undefined reference to `Mantid::Geometry::OCGeometryHandler::~OCGeometryHandler()'

Another problem is that the generated unit test file contains this line:

using namespace Mantid::API;

which will only compile if something that imports something from Mantid::API is tested.
