Howto build:
~~~~~~~~~~~~
In order to sucessfully build the gr-specest modules you will need:
* cmake > 2.8
* swig
* libgnuradio-core
* libuhd
* gfortran (others might work as well, not tested)
* liblapack-dev
* libblas-dev

A note on Fortran: The fort77 compiler does *not* work here. However, if
you have both a current gfortran version and the old fort77 installed, it
might happen that CMake detects the wrong version. Either specify the
compiler manually or delete the old Fortran compiler.

After checking out the code from the repository, change to the gr-specest
directory. If you want to build with a different compiler such as clang
you might have to do something like:

export CXX=clang++
export CC=clang

before.

Create a new directory e.g. 'build' to do an out of source build:

mkdir build
cd build
cmake ../
make
make install

For more information refer to the cmake documentation.

Howto add your own blocks to the GNU Radio Spectral Estimation Toolbox:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* Your C++ or Fortran code goes into lib/
* Your Python code and your Python unittests go into python/
* Your swig stuff goes into swig/

Adding a new C++ file that does not depend on Armadillo:
--------------------------------------------------------
* As stated above, C++ code goes into lib/
* Your QA code goes into qa_specest_yourblockname.{h,cc}
  respectively qa_specesti_yourblockname.{h,cc} if it is an
  implementation block
* Your code for the actual block goes (usually) into
  specest_yourblock.{h,cc}
* To include your files in the buildsystem add them to the file
  lib/CMakeLists.txt by editing the following variables:
    * CXX_SRCS (Sourcecode)
    * CXX_QA_SRCS and CXX_QA (QA source and names of tests (i.e. your class name))

Adding a new C++ file that does depend on Armadillo:
-----------------------------------------------------
* For now, don't do it, as we're trying to get rid of the dependency sooner or later

Adding a new Fortran file:
--------------------------
* As stated above, Fortran code goes into lib/
* Up to now we're wrapping the fortran code into specesti_ implementation blocks
  so we don't have unittests to directly test the fortran code
* Your code goes into specesti_{c,z,f,d}yourblock.f90
* To include your files in the buildsystem add them to the file
  lib/CMakeLists.txt by editing the following variables:
    * F_SRCS (Sourcecode)

Adding a new Python file:
--------------------------
* As stated above, Python code goes into python/
* If it's a QA/test file, add it to python/CMakeLists.txt
  in the PYTHON_QA variable
* If it's a file that contains code that needs to be installed later, add it to python/CMakeLists.txt
  in the SPECEST_PY_SRCS variable

Swig integration:
-----------------
This works basically the same as with the autotools based build system
* Drop your *.i files into swig/ directory
* include them into the specest.i as it has been with the others
