Several cmake improvements

[emmenlau]

Still work in progress.

[papadop]

Can you ask a pull request to the New cmake branch ? If you can drop the getopt CMakeLists.txt that would be great as I already added the one from OpenMEEG-matio. Thank's for all the suggestions. I skimmed through them quickly and they seem to be nice improvements (which also show that we never built OpenMEEG-mtio on windows with many of the options)
.

Dear @papadop , I just pulled in your latest changes and rebased my changes on top of yours. I also removed my getopt CMakeLists.txt. I will test now and then push the update.

[emmenlau]

A minor thing: your getopt library is called gnu and is installed in the target directory. Would it be ok to just call it getopt or getopt_long instead?
And is it required to install the getopt library, or is it only for building the tools?

[papadop]

The getopt library is needed to build the tools and the testing utility test_mat. Whether it is needed to install it depends on the way it is linked into the executables. I tend to think that it is linked dynamically, which means that if you install the tools or the test_mat utility then you also need to install the getopt lib.

[papadop]

As for the name, I do not think I changed anything. But I do not know where I got this. Looking at the CMakeLists.txt it seems that we build a static library, so there is no need to install it and we can name it getopt which is probably better than gnu indeed.

[emmenlau]

Great, I agree. Then I'll make these minor changes too.

Is this still being worked on? If not, I propose to close it w/o merge?

[papadop]

I intend to continue on working on thé branch... Please do not close it.

Any updates? If matio supported add_subdirectory() from a parent CMake project, this would be great and would mean the that a project could build matio directly if needed.

[tbeu]

Sorry, no news here. Autotools and VS solutions are the supported build environments. See https://github.com/tbeu/matio#20-building

[massich]

I would close this one in favor of #107

[tbeu]

Let's see it it works automatically once I merge #107.

Doing so.
