I understand why CMake cannot resolve the issue in a single call to configure. However...
how tricky/hard/impossible would it be to alter/rape the generate stage of CMake to handle this issue? Let's say I wanted to create a Win32 and an x64 platform inside a solution/project. Then I would start a VS command prompt for the native 64 and 32 bit compilers. I'd start a CMake GUI from both (or use the command line, whatever) and configure once a 32-bit and once a 64-bit solution. The tricky part comes here: both CMake instances have their output directory set to the same directory. I could image the generate stage (or even later internally just when writing the output files), that when I generate let's say the 32-bit first, it sees an empty directory, creates all neccessary files, and it's done. When I hit generate the second time on the 64-bit configuration, it finds solution files with Win32 set as platform. Instead of overwriting all the project and solution files, it could insert into the xml code it's own x64 platform and leave the others as it is. This way both platforms would compile and link the proper libraries and dependencies. Having met CMake as not an end-user only 3 weeks ago, I have little knowledge of the intimacies of the configuration cache for example, so I could imagine that having two different configuration set onto the same output directory could cause mishaps, but that is why I ask the black-belt people here. I have not used other IDEs throroughly, but I can image CodeBlocks or XCode has got their own equivalent (or maybe not) of platforms beside regular build targets. Could this setup of configurate/generate serve as a solution to our problem? Is there hope of it being implemented? Or are there conceptual errors along the way that I have not come to realise? (I could image changing the behavior of "shoot first, ask later", namely do not check anything, just overwrite whatever we find in the target dir, could be misleading in the sense that one would expect such behavior from all generators, but instead the VS generator parses the found solution/project files, and inserts code into it if the platforms differ, rather than overwriting the entire thing. I believe these behavioral differences could be overlooked, if one could make multi-platform solution files.) Ideas? Suggestions?
