We want to use configure and qt-configure-module when building in Coin, rather than pure cmake and qt-cmake. There are a few benefits: - CI tests the scripts, making sure we don't introduce regressions - CI uses the same scripts that we mention in our documentation for developers to use - The platform configurations become a bit less verbose and easier to read due to less shouty-case CMake options To ensure a more gradual porting, Coin will only use the new instructions if the 'UseConfigure' feature is set on a platform configuration in qt5.git. This allows going back to the old instructions in case if something isn't working properly. Due the opt-in, we need to support both old and new instructions in the implementation. The change strives to remove as much duplicate code as possible, by moving it into common includes. The README.md is updated to mention the overview of how the different environment variables are used. There are a few important things to point out. 1) Because during the porting we have to allow mixing of the old style and new style, platform configs have to separate CMake-style options from configure-style options in different environment variables. Otherwise the instructions wouldn't be able to create a valid configure call, where all CMake-style options have to go at the end after a double dash --. After all platform configs are ported to the new style, it should be possible to combine all the options in a single environment variable if that is desired, but it will require another round of porting to remove all the '-D' prefixes in CMake-style options, and just use regular variable assignment which configure supports. e.g. -DQT_BUILD_EXAMPLES=ON becomes QT_BUILD_EXAMPLES=ON, which can be mixed in-between configure-style args. 2) Configure is more strict in that it doesn't allow passing unknown options. Due to that, we can't pass non-qtbase configure options via NON_QTBASE_CONFIGURE_ARGS. qt-configure-module would error out in the repos where the configure option is unknown. Because we don't have a Coin configure variable for each repo, we circumvent the issue by continuing to pass CMake-style options via NON_QTBASE_CMAKE_ARGS instead, which does not do validation checks. In the future, we could introduce a configure flag that disables the validation checks.
