undefined reference to `ilutGLScreen' about devil

[JMendyk]

As @JohnKendrick pointed out, indeed ILUT_USE_OPENGL is defined in devil/DevIL/include/IL/ilut_config.h. However this file is included only in devil/DevIL/include/IL/ilut.h only if we are compiling on windows:

#if (defined(_WIN32) || defined(_WIN64))
	#if (defined(IL_USE_PRAGMA_LIBS)) && (!defined(_IL_BUILD_LIBRARY))
		#if defined(_MSC_VER) || defined(__BORLANDC__)
			#pragma comment(lib, "ILUT.lib")
		#endif
	#endif

	#include <IL/ilut_config.h>
#endif

After manually editing top-level CMakeLists.txt and adding add_definitions(-DILUT_USE_OPENGL) project builds successfuly and ilutGL* functions are references properly.

I hope this insight will be helpful.

I'll try to take a look at this soon. I haven't focused on ILUT with the latest updates, and it seems something may have broken with the switch to CMake.

@DentonW Have you been able to look deeper into this issue?

In my case I wasn't able to use ilutGLBindTexImage but after checking contents of libILUT.so I found out that it has no functions starting with ilutGL.

Hi, this is still a problem using the vcpkg method of installing DevIL.
