	#1  elgaton 02:48 Nov 02, 2015	If FLTK is built with autotools, FLTKConfig.cmake is not created nor installed. This forces developers using CMake as their build system and on a distribution using autotools in the FLTK package build file to recompile FLTK or create FLTKConfig.cmake manually in order to link their software with the library.
	#2  AlbrechtS 08:33 Nov 03, 2015	Thanks for the report. I can see your point: Linux distros use (and _should_ currently use) autotools to build FLTK. It would be nice to ship the CMake files with the distro so users can use CMake to build their own software, although the shipped and installed version was built with autotools. That said, I'm afraid we can't resolve this issue quickly. We'd need to generate three files (actually six, see below):  - FLTKConfig.cmake (as mentioned by the OP)  - FLTK-Targets.cmake  - UseFLTK.cmake or (maybe, if possible) one file containing everything in these three files. We need to generate two versions of each file to have a complete CMake build environment: one file for use with the build directory and one file for use with the install directory. All these (six) files are generated by CMake and contain CMake-specific code and variables. We'd need to replicate these files as templates for the autotools build system and update them regularly if the CMake build system changes these generated files. That would be possible, but not easily maintainable. Currently we don't support this scenario. CMake support is still experimental and incomplete. We can try to do this later, but please don't hold your breath. It's very likely that this will not happen before FLTK 1.4.0.
	#3  AlbrechtS 08:37 Nov 03, 2015	Changed priority from 2 (low) to 1 (RFE).
	#4  AlbrechtS 07:53 Aug 08, 2016	Pushed from 1.3-feature to 1.4-feature.
	#5  AlbrechtS 15:11 Jan 16, 2023	Assigned to myself. Please see also GitHub Issue #655 "CMake fixes". https://github.com/fltk/fltk/issues/655
	#7  AlbrechtS 08:47 Nov 17, 2023	FLTKConfig.cmake can't be built by the autotools system because it would need too many internal information that only CMake has. The short term "solution" for users is to build FLTK with CMake. Hopefully Linux distributors and others will do this once FLTK 1.4.0 will be released. Please note that autotools (configure/make) builds will not be supported starting with FLTK 1.5.0 (or any version higher than 1.4.x).
