cmake: new build tool this step unify the builing system for all platforms (windows, linux, osx and *BSD) * Requirements: - gcc/clang (C/C++ compiler) (in debian build-essential) - cmake (in debian cmake) - git if you build from source (in debian git) - posix threads ** Requirements on *BSD/macOS: - portaudio ** Optional Requirements: - gpsd (in debian libgps-dev) - libhamlib (in debian libhamlib-dev) ** Optional Requirements in Linux - udev (in debian libudev-dev) - alsa (in debian libasound2-dev) * Main changes: - version is now set only on CMakeLists.txt and automatically used on the code - cpu flags are auto-discovered in the default build and it works on gcc/clang/msvc on x86/x86_64/arm; you can force cpu flags with -DFORCE_SSE=1 for example (see CMakeLists.txt on root) - use a more "complex" tag on generic.conf to facilitate parsing by cmake (not more platform dependent). Now it is %C% or %R% for example - target `tocalls-symbols` is now called `data-update` - created debian/ directory to contains files to use debuild * Example to build: mkdir build && cd build cmake .. make make install make install-conf then you have the binary files on src/ and in the system directory * CMake options (see the head of CMakeLists.txt) - FORCE_SSE force sse instruction - FORCE_SSSE3 force ssse3 instruction - FORCE_SSE41 force ssse4.1 instruction - OPTIONAL_TEST compile optional test (might be broken) - BUILD_TESTING enable tests (ctest framework) - CMAKE_INSTALL_PREFIX if you want to change your install path prefix for example: cmake .. -DOPTIONAL_TEST=ON
