# Notes: # # Author: Paul Harris, June 2012 # Additions: Joakim Soderberg, Febuary 2013 # # Supports: building static/shared, release/debug/etc, can also build html docs # and some of the tests. # Note that its designed for out-of-tree builds, so it will not pollute your # source tree. # # TODO 1: Finish implementing tests. api tests are working, but the valgrind # variants are not flagging problems. # # TODO 2: There is a check_exports script that would try and incorporate. # # TODO 3: Consolidate version numbers, currently the version number is written # into: * cmake (here) * autotools (the configure) * source code header files. # Should not be written directly into header files, autotools/cmake can do # that job. # # Brief intro on how to use cmake: # > mkdir build (somewhere - we do out-of-tree builds) # > use cmake, ccmake, or cmake-gui to configure the project. for linux, you # can only choose one variant: release,debug,etc... and static or shared. # >> example: # >> cd build # >> ccmake -i ../path_to_jansson_dir # >> inside, configure your options. press C until there are no lines # with * next to them. # >> note, I like to configure the 'install' path to ../install, so I get # self-contained clean installs I can point other projects to. # >> press G to 'generate' the project files. # >> make (to build the project) # >> make install # >> make test (to run the tests, if you enabled them) # # Brief description on how it works: # There is a small heirachy of CMakeLists.txt files which define how the # project is built. # Header file detection etc is done, and the results are written into config.h # and jansson_config.h, which are generated from the corresponding # config.h.cmake and jansson_config.h.cmake template files. # The generated header files end up in the build directory - not in # the source directory. # The rest is down to the usual make process. cmake_minimum_required (VERSION 2.8) # required for exports? cmake_minimum_required (VERSION 2.8.6) project (jansson C) # Options option(JANSSON_BUILD_SHARED_LIBS "Build shared libraries."
