# MatLab links it's own version of hdf5 libraries and thus overides the dynamic 
# linked versions provided by the build system. This leads to a segfault in 
# MatLab if both hdf5 versions are different from each other.
# Solution: Static link HDF5 Library into the mexfiles
# (found at http://stackoverflow.com/questions/2188658/shared-library-locations-for-matlab-mex-files)
# TODO: Let cmake set correspondig CXX_FLAGS for static linking of the found hdf5 libraries.
# "-Wl,-Bdynamic -lstdc++" is required as libstdc++ does not support static linking into a dynamic library
#message("hdf5 libs: ${HDF5_LIBRARIES}")
