config.h.cmake.in incomplete: crash on Windows 7, AMD FirePro M4170 #153

Original report by Bastiaan Veelo (Bitbucket: veelo, GitHub: veelo).

Our program crashes consistently upon use of certain functions on very few installations of Windows, since using the CMake build.

Using a debug build, the assertion on row 3380 of src\glue\gl.cpp fails, for glue->glNormalPointer. After setting set COIN_DEBUG_GLGLUE=1, we see the following errors:

Coin warning in coin_wgl_getprocaddress(): couldn't get hold of any workable module handle for picking up OpenGL symbols

These are generated in src\glue\gl_wgl.cpp:coin_wgl_getprocaddress() and indicate that there is a problem in src\glue\dl.cpp:cc_dl_handle_with_gl_symbols().

The problem, I presume, is that if cc_dl_process_handle() fails, cc_dl_coin_handle() and cc_dl_opengl_handle() are tried, which default to using POSIX library names; unless they have actually been defined correctly in config.h. The erroneous defines in this case are

#define COIN_SYSTEM_LIBRARY_NAME "libCoin.so"
#define DYNAMIC_LIBRARY_EXTENSION ".so"
#define OPENGL_SYSTEM_LIBRARY_NAME "libGL.so"

Do grep -r OPENGL_SYSTEM_LIBRARY_NAME * in the Coin root directory to find correct defines for various platforms.

To me it seems these are not the only defines that have not yet been ported to CMake.
