A little tool to convert Xcode projects to cmake CMakeLists.txt.
You can specify the target to export. If you don't specify a target, all targets are exported. It doesn't do a perfect job, but it's better than doing it all by hand. It can convert most targets, but it will do better with libraries and tools or frameworks.
This is useful for "one-shot" conversions. For continous conversions from Xcode to cmake, use mulle-sde.

Use the homebrew package manager to install it, or build it yourself with Xcode:
brew install mulle-kybernetik/software/mulle-xcode-to-cmake
Get foundation-developer installed and then build mulle-xcode-to-cmake with:
mulle-sde clean cache
mulle-sde craft --release
mulle-sde run mulle-make install --prefix /usr/local/bin
It is also possible to build with GNUstep using cmake and the
CMakeLists.txt file generated by mulle-xcode-to-cmake itself. After
checking out the sources, change into the source directory and then:
mkdir build && cd build
cmake -Wno-dev ..
make
sudo make install
On Mac this should work without installing any additional dependencies. On other platforms it is suggested to install a recent clang version (5 or later) and you will need libobjc and the gnustep-base developer package, both from GNUstep (or another implementation of the ObjC runtime and the Foundation library).
On Windows, it is a bit tricky : please refer to this little guide here
usage: mulle-xcode-to-cmake [options] <commands> <file.xcodeproj>
Options:
-2 : CMakeLists.txt includes CMakeSourcesAndHeaders.txt
-a : always prefix cmake variables with target
-b : suppress boilerplate definitions
-d : create static and shared library
-f : suppress Foundation (implicitly added)
-i : print global include_directories
-l <lang> : specify project language (c,c++,objc) (default: objc)
-n : suppress find_library trace
-p : suppress project
-P <prefix> : prefix filepaths
-r : suppress reminder, what generated this file
-s <suffix> : create standalone test library (framework/shared)
-t <target> : target to export
-u : add UIKIt
-w <name> : add weight to name for sorting
Commands:
export : export CMakeLists.txt to stdout
list : list targets
sexport : export CMakeSourcesAndHeaders.txt to stdout
Environment:
VERBOSE : dump some info to stderr
List all project targets:
$ mulle-xcode-to-cmake list mulle-xcode-to-cmake.xcodeproj
mulle-xcode-to-cmake
mullepbxCreate "CMakeLists.txt" for target mullepbx leaving out some
boilerplate template code. Invoking mulle-xcode-to-cmake -b export mulle-xcode-to-cmake.xcodeproj yields:
