pkgconfig file on Windows seems broken

[wolfv]

We are currently patching the pkgconfig file for Windows. https://github.com/conda-forge/libode-feedstock/blob/master/recipe/modify-dotpc-win.patch We use a -I:{includedir} syntax that accidentally adds an extra : at the front of the path. These pkgconfig files are also read by e.g. CMake which is where this breaks (in OMPL).

I wonder if hte following patch would be better?

@traversaro maybe you know if this would work on Windows?

If we ship a ode_double.lib library, this new version of the patch should work fine on Windows as well.

Yeah we do because of this condition in the WIN32 block:

Maybe I can use templating as well ... let me try! :)
