[Minotaur] Minotaur help

[Ashutosh Mahajan]

Dear Cristina

You will have to tell cmake to look into that third-party lib folder for the libraries.

I have put up instructions on the wiki now:
https://wiki.mcs.anl.gov/minotaur/index.php/Compiling_MINOTAUR#Missing_BLAS_and_LAPACK_Libraries

Here's a copy:
The error messages "cannot find -llapack" and "cannot find -lblas" will be
seen after the "make" command if blas and lapack libraries are not available
in your system. There are two ways around it.

 1. Install blas and lapack in the system. On Debian or Ubuntu, it means doing
    "apt-get install libblas-dev".
 2. Use blas and lapack libraries available in the third-party directory
    of the Minotaur Libraries and Header Files package. 

For the second option, add the flag
 -DCMAKE_EXE_LINKER_FLAGS=-L/path/to/minotaur-VER-dev-linux-ARCH/third-party/lapack-3.4.0/lib
to the cmake command for compiling. Then run make and make install again.

If you used ccmake, then run ccmake again, and press 't' to toggle advanced
options. Add
 -L/path/to/minotaur-VER-dev-linux-ARCH/third-party/lapack-3.4.0/lib
to the "CMAKE_EXE_LINKER_FLAGS" field. Then press 'c' to configure,
'g' to generate and 'q' to quit. Run make and make install.
