When converting from autoconf, the generation of "config.h" files can be complex. You may wish to examine the CMake scripts within the gcc-xml project at gcc-xml (XML output of gcc's internal representation). The project builds a modified gcc compiler using CMake. This is an impressive feat of autoconf conversion.
For example, the HAVE_THIS/HAVE_THAT defines used within autoconf projects can be overwhelming when converting a large project. Below is a snippet from the "config.h.in" file within gcc-xml:
/* Define to 1 if you have the `bcopy' function. */ #cmakedefine HAVE_BCOPY @HAVE_BCOPY@ /* Define to 1 if you have the `bsearch' function. */ #cmakedefine HAVE_BSEARCH @HAVE_BSEARCH@ /* Define to 1 if you have the `bzero' function. */ #cmakedefine HAVE_BZERO @HAVE_BZERO@
While not a drop-in tool, their scripts are an excellent starting point. Be sure to reference the code from their CVS repository instead of the out-of-date tarball listed.
