CMake Compile: Build fails with Unresolved Externals

[RMWChaos]

This failure is very similar to the problem resolved in Trac Ticket #574, which involved a straight NMake build (no CMake component). So likely, this has to do with the recent inclusion of geos\src\util\interrupt.cpp.

Following instructions on http://trac.osgeo.org/geos/wiki/BuildingOnWindowsWithCMake; Building with SDK 7.0 x64 (MSVC 2008).

1. Downloaded svn_trunk

2. Copied geos\src\util\triangulate directory from nightly snapshot (missing in svn_trunk)

3. Ran C:\temp\geos\build> cmake -G "NMake Makefiles" C:\temp\geos

4. Ran C:\temp\geos\build> nmake /f makefile MSVC_VER=1500

Correction: geos/src/triangulate missing (not geos/src/util/triangulate)

[strk]

The official build system is the automake one. Please only file tickets against cmake if willing to provide a patch (sorry).

@strk

Feel free to discard CMake tickets, perhaps you can clarify the policy on wiki or just remove the wiki and CMake stuff from SVN to avoid confusions.

Patch submitted to #611 should fix the problem, needs testing.
