Building/Testing with new CMake build system
--------------------------------------------
CMake is a C++ Makefiles/Solution generator that can be downloaded from:

sudo apt-get install cmake

Building and testing with new CMake
-----------------------------------
[CMake][] is a C++ Makefiles/Solution generator. It is usually available on most
Linux system as package. On Ubuntu:
sudo apt-get install cmake
[CMake]: http://www.cmake.org
Note that Python is also required to run the JSON reader/writer tests. If
missing, the build will skip running those tests.
When running CMake, a few parameters are required:
- a build directory where the makefiles/solution are generated. It is
also used to store objects, libraries and executables files.
- the generator to use: makefiles or Visual Studio solution? What version
or Visual Studio, 32 or 64 bits solution?
Generating solution/makefiles using cmake-gui:
- Makes "source code" points the source directory
- Makes "where to build the binary" points to the directory to use for
the build.
- Click on the "Grouped" check box
- Review JsonCpp build option (tick JSONCPP_LIB_BUILD_SHARED to build as
a dynamic library)
- Click configure button at the bottom, then the generate button.
- The generated solution/makefiles can be found in the binary directory.
* a build directory where the makefiles/solution are generated. It is also used
to store objects, libraries and executables files.
* the generator to use: makefiles or Visual Studio solution? What version or
Visual Studio, 32 or 64 bits solution?
Steps for generating solution/makefiles using `cmake-gui`:
* Make "source code" point to the source directory.
* Make "where to build the binary" point to the directory to use for the build.
* Click on the "Grouped" check box.
* Review JsonCpp build options (tick `JSONCPP_LIB_BUILD_SHARED` to build as a
dynamic library).
* Click the configure button at the bottom, then the generate button.
* The generated solution/makefiles can be found in the binary directory.
Alternatively, from the command-line on Unix in the source directory:
mkdir -p ../build/debug
cd ../build/debug
cmake -DCMAKE_BUILD_TYPE=debug -DJSONCPP_LIB_BUILD_SHARED=OFF -G "Unix Makefiles" ../../jsoncpp-src
make
Running "cmake -h" will display the list of available generators (passed as -G option).
By default CMake hides compilation command-line. This can be modified by specifying:
-DCMAKE_VERBOSE_MAKEFILE=true when generating makefiles.
mkdir -p ../build/debug
cd ../build/debug
cmake -DCMAKE_BUILD_TYPE=debug -DJSONCPP_LIB_BUILD_SHARED=OFF -G "Unix Makefiles" ../../jsoncpp-src
make
Running `cmake -`" will display the list of available generators (passed using
the `-G` option).
By default CMake hides compilation commands. This can be modified by specifying
`-DCMAKE_VERBOSE_MAKEFILE=true` when generating makefiles.
