#
# 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.
