svn commit: r1920560 - /subversion/branches/cmake/CMakeLists.txt

Author: rinrab
Date: Wed Sep 11 12:18:44 2024
New Revision: 1920560

URL: http://svn.apache.org/viewvc?rev=1920560&view=rev
Log:
On the 'cmake' branch: swig: Generate external runtimes and wrap headers
for swig.

The generation will be done by creating CMake targets, which will invoke
the Python script.

* CMakeLists.txt
  (swigincludes): Update proxy path to one with the generated headers.
  (external-swig): Enumerate all headers, add a custom command for each
   header, and create a target that depends on all that commands.
  (swig_target_external_runtime): New function, that will create custom
   command for generating external runtime and add sources to the targets.
  (swig.python, swig.perl): Invoke swig_target_external_runtime for these
   targets to generate external runtimes.
