Bugfix
Included the external/* in cmake
Minor bugfix
Grrr, forgot to add a file
Seems that some users did not believe that FLENS is actually header-only and Makefiles only for using the test suites.  So I modified the makefile a bit.  A plain 'make' now does nothing at all.  Only 'make check' builds and runs the test suites.
Okay, we even display in case of 'make' or 'make install' a note about the fact the we are header only :-)
Just another tweak of the makefile
Minor bugfix.  An assertion for a matrix assignment B=A was too restrictive in case that B was empty
Minor bugfix:  A = conjugate(A) did not work for some stupid reason ...
Added FLENS-BLAS function for conjugating GeMatrix.
