IMPORTANT message for everybody lurking on this list. Revision 12419 (referred to below) updates the minimum acceptable CMake version to 2.8.9. This effectively updates all CMake policies (interpretations of CMake logic) so revision 12419 needs lots more testing. See the commit message for revision 12419 for additional comments about this.

Hi Arjen: I am afraid the combination of the issues below that I have noted means another test is requested. What a big surprise. :-) Here are the details: Your cmake.out file reveals some important issues. 1. -- The C compiler identification is GNU 4.5.3 That must mean you are using a rather old version of Cygwin that needs to be updated (or better yet installed from scratch to preserve your old version for comparison). The version of gcc should be at least 4.7.x from my experience with MinGW/MSYS. 2. The warning concerning CMAKE_LEGACY_CYGWIN_WIN32 not being set to 0. It was being set (to OFF, but that should not matter) before, but I think it was probably done in the wrong order. As of revision 12419 I have adopted the same order as used for the build of CMake itself and that should hopefully quiet this message. By the way, I am pretty sure there are no practical consequences to this warning message because the resulting WIN32 variable is false and the resulting CYGWIN variable is true. But for your retest, please check that the new reordering has quieted the message. 3. WARNING: ENABLE_DYNDRIVERS is OFF. It is important that your retest be done with ENABLE_DYNDRIVERS ON since that is the most heavily tested version of PLplot on all platforms. Once ENABLE_DYNDRIVERS ON works on Cygwin, then by all means try other possiblities such as ENABLE_DYNDRIVERS OFF. Your make.out file reveals one extremely important issue. CMake generated no -rpath options for linking! There is some anecdotal evidence on the web that -rpath actually works on Cygwin, but clearly the CMake engineers (at least for version 2.8.9 which you are currently using) do not trust -rpath on Cygwin or are unaware of that capability because CMake doesn't even try to use the rpath option on that platform. So only the dll workaround will work, and I have no clue how your previous Cygwin tests worked at all unless you manually did something like that dll workaround. As of revision 12420 I have changed our build system logic so that the dll subdirectory workaround is used only for shared libraries and for WIN32_OR_CYGWIN. I have now deployed an additional variable (USE_DLL_SUBDIRECTORY) to control when this workaround is used so any further changes in our policy concerning this will only require a change in one place (where USE_DLL_SUBDIRECTORY is defined). Please give revision 12420 a try with ENABLE_DYNDRIVERS ON. Win or lose, I would again like to see complete results, i.e, all the *.out files (using VERBOSE=1), and the CMakeCache.txt file. It didn't matter this time, but you forgot to include that latter file in the current tarball. Can you automate collection of files in that tarball with a script and also automate the use of VERBOSE=1 so I always get from you the full results requested? Also, if you make it a practice to automatically collect full results of the Cygwin build in a tarball, they should be useful to you in future when you are wondering what the last build and test results were for the Cygwin platform.
