CMAKE issues and Improvement Ideas

[mcuee]

Change the issue to CMAKE improvement.

1. -D HAVE_SWIG=0 does not work.
2. `-D CMAKE_INSTALL_PREFIX:PATH=/xxx/xxx" does not work for SWIG/PYTHON binding.

• avrdude Python binding configuration improvement #1914

3. Library detection improvement -- using pkg-find to find the libraries

• CMake improvement -- using pkg-find to find the libraries #1797

Original intention of this ticket is to check the following.

1. It will be good to be able to define build option in the command line.

Something like the following.

extra_enable="-D BUILD_DOC=1 -D HAVE_LINUXGPIO=1 -D HAVE_PARPORT=1 -D HAVE_LINUXSPI=1" ./build.sh

As of now, the above is not working, the user is expected to edit build.sh to use the function.

2. The above will also be good if the user wants to define installation prefix.

Hmm, actually there is an option -f to pass the extra build options to CMAKE.

BTW, the following is the dependancy with TEX distribution I mentioned before.

You don't have a working TeX binary (tex) installed anywhere in
your PATH, and texi2dvi cannot proceed without one.  If you want to use
this script, you'll need to install TeX (if you don't have it) or change
your PATH or TEX environment variable (if you do).  See the --help
output for more details.

For information about obtaining TeX, please see http://tug.org/texlive,
or do a web search for TeX and your operating system or distro.

On Debian you can install a working TeX system with
  apt-get install texlive

We also need one more package texi2html. If not, the following error will happen.

Somehow the following does not work.
./build.sh -f "-D HAVE_SWIG=0" is supposed to disable the building of python bindings.

Well, to me, build.sh is mostly a tool to help getting things to work without memorizing too many complicated details.

So for things that appear to be frequently asked for, rather invent a new commandline option, and explain it in the -h output so people can start using it.

-f was merely intended to allow fine-tuning – which could perhaps also include options that eventually might deserve their own commandline flag. ;-)
