[gdal-dev] cmake status update - 99% good news!

[Joaquim Manuel Freire Luís]

Hi,

I made also an attempt on Windows and so far my findings are:

The docs say that the PROJ variables should be 

PROJ_INCLUDE_DIR
PROJ_LIBRARY_RELEASE

But the lib var must in fact be

PROJ_LIBRARY

Couldn't yet find a way to build with HDF5, ECW and MRSID, which I can do with no problems with the current nmake solution.
For the rest, I haven't test anything but it builds fine and a quick `Dependency` analysis shows no issues.

Joaquim

I have started testing cmake support on gdal master.
My approach is

  1) Build gdal from git using cmake.

  2) Be able to create a release tarball (not actually a release of
  course) from master in order to use for building with pkgsrc.

  3) Build the release using autoconf, basically unchanged pkgsrc
  control files execpt for version, and run tests and check qgis
  functionality.

  4) Convert the package control files to use cmake instead of autoconf
  and test again.  This involves our "gdal-lib" and "py-gdal" packages.

In step 1, I have so far found one problem, an incorrect INCLUDE variable for poppler.  I have created a pull request with a simple fix:
  https://github.com/OSGeo/gdal/pull/5161

For step 2, as Even suggested would be the case, I ran into a number of small portability issues (some makefiles need GNU make, even though the cmake makefiles don't) and missing documentation (breathe and swig (4?) are required to run mkgdaldist.sh).  None of these are a big deal and the list is pretty small for what I think might be the first time the script has been used on a different operating system.  I have a branch in progress and will submit a PR when it settles down.  The changes are minor.

For step 3, I've been able to build the release, but haven't tested yet.
