Hi All, Is there a way for CMake to search for macro definitions in header files without doing a try_run? The reason I'm asking is that eventually I'll require FindPython.cmake to report the version of python that it finds. But I don't want to do this by checking the directory names (which is unreliable) or by doing a try_run (for the sake of cross-compilation). Running the python executable itself to find the version is also out, due to cross-compilation.
For the VTK wrappers I've written a pseudo-preprocessor (vtkWrapPreprocess.c) that does essentially what I need, but not at configure time. I'm thinking of the same thing for CMake... a simple built-in preprocessor that can emulate a compiler and give cmake access to macro definitions without the need for a try_run. Or equivalently the real compiler could run its preprocessor stage and then present the results to cmake. The main thing is to avoid the try_run. Any thoughts? - David _______________________________________________ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake
