  • MSVC (VS 2017 15.0)
• CMake 3.1.3
• SDL v2.0.4

CMake variables:

• CMAKE_BUILD_TYPE
  Selects which build(s) to compile. Use semicolon to separate entries. Usually it’s Release. For other values see CMake documentation.

• CMAKE_INSTALL_PREFIX
  Selects location where to install files to.

• BSTONE_PANDORA
  Enables build for Open Pandora.

• BSTONE_USE_PCH
  If enabled utilizes precompiled headers to speed up the compilation.
  Note: Visual C++ only

• BSTONE_USE_STATIC_LINKING
  If enabled links modules statically to avoid dependency on system and custom libraries at run-time.

• BSTONE_USE_MULTI_PROCESS_COMPILATION
  Enables multi-process compilation if supported.

• SDL2W_SDL2_DIR
  Defines directory with SDL2 CMake configuration file or with official SDL2 development Windows build.

Notes:

• Use ON value to enable option and value OFF to disable option.

6.1 - Generic instructions for Linux-based system or build environment (MinGW)

1. Install minimum required software described above.

2. Obtain source code and extract it (if necessary) into some directory. For our example we will use working directory ~/bstone-x.y.z.

3. Make directory ~/bstone-x.y.z/build current.

4. Generate Makefile.
   cmake ../src -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=~/bstone-x.y.z/build/install

5. Build and install: make install

6. On success you will find executable and text files in the directory ~/bstone-x.y.z/build/install.
