Summary0014954: feature request: add FindRAGEL parser generator module
DescriptionCMake already comes with support for parser-generators/compiler-compilers like Flex and Bison (i.e. FindFLEX/FindBison).

But currently, it does not support the Ragel state machine compiler/parser-generator (http://www.complang.org/ragel/ [^] ).

A google search shows that there is a need for such support - there are various projects using Ragel - and some projects which build with cmake reinvent the wheel, i.e. they ship custom cmake targets for ragel compilation.

I've created a FindRAGEL module for my needs - it is based on the FindBISON module distributed with cmake:

https://github.com/gsauthof/cmake-ragel [^]

Besides the small examples included in the above repository you can also see how the FindRAGEL module is used in another project - for multiple ragel files:

https://github.com/gsauthof/imapdl [^]

Please feel free to integrate the FindRAGEL module (or something to the same effect) into the cmake distribution.

Thanks for offering this module.

Please read CONTRIBUTING.rst at the top of the source tree:

 http://cmake.org/gitweb?p=cmake.git;a=blob;f=CONTRIBUTING.rst;hb=v3.0.0-rc6 [^]

It explains the preferred entry path is to send patches to the mailing list.

Please also read the cmake-packages(7) manual:

 http://www.cmake.org/cmake/help/v3.0/manual/cmake-packages.7.html [^]

and the cmake-developer(7) manual section on writing modules:

 http://www.cmake.org/cmake/help/v3.0/manual/cmake-developer.7.html#modules [^]

A few quick comments from glancing at the module:

- The documentation comment will need to be converted to the reStructuredText-based documentation system used in CMake 3.0 and above.
- Generally I prefer not to maintain APIs in find modules. The bison_target macro is a legacy API. Projects could call add_custom_command themselves. We can always add an API later if necessary but we can never remove one easily.

Please resolve these for the version to be posted to the list or ask on the list if you need help. Thanks!
