config BR2_PACKAGE_PYTHON_KIWISOLVER bool "python-kiwisolver" depends on BR2_INSTALL_LIBSTDCPP help Kiwi is an efficient C++ implementation of the Cassowary constraint solving algorithm. Kiwi is an implementation of the algorithm based on the seminal Cassowary paper. It is not a refactoring of the original C++ solver. Kiwi has been designed from the ground up to be lightweight and fast. Kiwi ranges from 10x to 500x faster than the original Cassowary solver with typical use cases gaining a 40x improvement. Memory savings are consistently > 5x. https://github.com/nucleic/kiwi comment "python-kiwisolver needs a toolchain w/ C++" depends on !BR2_INSTALL_LIBSTDCPP
