CMake: clean `CMAKE_{SOURCE,BUILD}_DIR`
Replace `CMAKE_SOURCE_DIR` and `CMAKE_BUILD_DIR` with different variables, or in some cases just remove them. For some function arguments, prepended `CMAKE_SOURCE_DIR` was removed without replacement. This includes: * Sources for `add_library` and `add_executable` (`ZIG_CPP_SOURCES` and `ZIG_WASM2C_SOURCES`) * Inputs for `configure_file` and `target_include_directory` * For arguments above, CMake already prepends `CMAKE_CURRENT_SOURCE_DIR` to them by default, if they are relative paths. Additionaly, it was removed from arguments of commands that have `WORKING_DIRECTORY` set to `PROJECT_SOURCE_DIR`, they will be similarly converted by CMake for us. Also: * Move project declaration to the top so that these variables are available earlier. * Avoid calling "git" executable if ".git" directory does not exist. * Swap "--prefix" and `ZIG_BUILD_ARGS` arguments in cmake/install.cmake to match same "zig2 build" command in CMakeLists.txt and allow overriding "--prefix" argument Signed-off-by: Eric Joldasov <bratishkaerik@landless-city.net>
