A modern C++ library for image synthesis using Max Gumin's Wave Function Collapse algorithm

Dependencies:

• A C++20 compiler (tested on gcc version 10.2.1 20210110 , Debian 10.2.1-6)
• CMake >=3.5 build system
• Doxygen documentation generator
• LCov extension to gcov coverage tester\

To build (library, documentation, and test executable) assumming the root directory is the working directory:

cmake --build ./build --config Debug --target all --

the --config Debug should be omitted in release, as it enables flags related to coverage testing and disables optimization.

A list of all targets that can be used instead of all

• wfcpp to compile WFCpp as a static library (part of all).
• main.exe to compile test executable (part of all).
• doc to build Doxygen documentation for WFCpp (part of all).
• run to run test executable (builds main.exe target).
• coverage to build LCov coverage report for test executable (builds run target).
• EasyBMP to compile EasyBMP as a static library (part of all).
• lodepng to compile lodepng as a static library (part of all).

Since it is not part of the all target, remember that to build the coverage report for the test executable, use:

cmake --build ./build --config Debug --target coverage

The --config Debug flag is required to build coverage.

To use this library, the easiest method is to use CMake for your project, and add a target_link_libraries(<target> wfcpp) command to your CMakeLists.txt file, where <target> refers to whatever executable you are compiling. CMake will ensure that you can access the library's headers by using angle bracket includes such as #include <Solver.h>. Alternatively, one can always build libwfcpp.a to link with using the wfcpp target, and copy-paste the library's headers to your own project. This is inadvisable but nontheless entirely possible.
