Raw Blame History

# 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.
