(Argh, I typed a long comment, then uploaded a file, now my comment is gone. This time I'll be more concise...)
- Unzip CMakeVS2010DirectoryTest.zip
- CMake it for VS 2010
- Open it in VS 2010
- Look at "CMake Rules"
-- Note they start with "cd someCode; ..." (cd to relative directory)
- Build Solution
- Get errors like this:

- If you keep building multiple times, eventually it will work as all the derived files get built
- So to test it again, make sure you "Rebuild Solution" or "Clean Solution" first
Sometimes CMake regenerates the project unnecessarily. To debug what / why, I enhanced some existing CMake std::cout statements to show the current directory and path to the file that forced the rebuild. I find it handy and it suggest adding it to CMake as well. It's in:
0001-Improve-clarity-of-messages-that-get-printed-when-CM.patch
However, you only want the cmake.cxx part of that patch.
(The cmSystemTools.cxx part of the patch was broken at the time and has since been improved... Basically that tweak causes RenameFile to keep .bak versions of every file so I can diff them - that helped me see why Visual Studio kept forcing me to reload projects... Probably not something you want permanently in CMake however.)
Thanks for looking into this! |
