[CMake] Compile CMakeCache.txt into shared library
Dear Cmake List, we would like to include a CmakeCache.txt file into our shared library. The reason is, that we would like to know what CMake options were used when compiling the library in case we have only the binary. Has anyone done something like this before and can give me some pointers? Thanks for any advice Valentin Note: I am not subscribed to this list, so pleae cc me in your response. -- Valentin Hänel Scientific Software Developer Blue Brain Project http://bluebrain.epfl.ch/ -- 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

Re: [CMake] Compile CMakeCache.txt into shared library
Hi, I'm not sure if I understand you correctly, but I would guess that in most cases you don't need to know _all_ cmake cache variables at runtime. If you really just need to know some specific variables, you would be much better off using a generated header file. See the documentation for configure_file for details on this. In short, you'd make a headerfile config.h.in with lines like this: #cmakedefine @my_magic_variable@ And in cmakeLists: configure_file( ${CMAKE_CURRENT_SOURCE_DIR}/config.h.in ${CMAKE_CURRENT_BINARY_DIR}/config.h ) Afterwards, you can include config.h in your shared library and you can use the value there...

Ah, yes. Thats great! Thanks!
