Struct cmake::Config

pub struct Config { /* fields omitted */ }

Builder style configuration for a pending CMake build.

Methods

impl Config

pub fn new<P: AsRef<Path>>(path: P) -> Config

Creates a new blank set of configuration to build the project specified at the path path.

pub fn generator<T: AsRef<OsStr>>(&mut self, generator: T) -> &mut Config

Sets the build-tool generator (-G) for this compilation.

pub fn cflag<P: AsRef<OsStr>>(&mut self, flag: P) -> &mut Config

Adds a custom flag to pass down to the C compiler, supplementing those that this library already passes.

pub fn cxxflag<P: AsRef<OsStr>>(&mut self, flag: P) -> &mut Config

Adds a custom flag to pass down to the C++ compiler, supplementing those that this library already passes.

pub fn define<K, V>(&mut self, k: K, v: V) -> &mut Config where
    K: AsRef<OsStr>,
    V: AsRef<OsStr>, 

Adds a new -D flag to pass to cmake during the generation step.

pub fn register_dep(&mut self, dep: &str) -> &mut Config

Registers a dependency for this compilation on the native library built by Cargo previously.

This registration will modify the CMAKE_PREFIX_PATH environment variable for the build system generation step.

pub fn target(&mut self, target: &str) -> &mut Config

Sets the target triple for this compilation.

This is automatically scraped from $TARGET which is set for Cargo build scripts so it's not necessary to call this from a build script.

pub fn no_build_target(&mut self, no_build_target: bool) -> &mut Config

Disables the target option for this compilation.

pub fn host(&mut self, host: &str) -> &mut Config

Sets the host triple for this compilation.

This is automatically scraped from $HOST which is set for Cargo build scripts so it's not necessary to call this from a build script.

pub fn out_dir<P: AsRef<Path>>(&mut self, out: P) -> &mut Config

Sets the output directory for this compilation.

This is automatically scraped from $OUT_DIR which is set for Cargo build scripts so it's not necessary to call this from a build script.

pub fn profile(&mut self, profile: &str) -> &mut Config

Sets the CMAKE_BUILD_TYPE=build_type variable.

By default, this value is automatically inferred from Rust's compilation profile as follows:

• if opt-level=0 then CMAKE_BUILD_TYPE=Debug,
• if opt-level={1,2,3} and:
  • debug=false then CMAKE_BUILD_TYPE=Release
  • otherwise CMAKE_BUILD_TYPE=RelWithDebInfo
• if opt-level={s,z} then CMAKE_BUILD_TYPE=MinSizeRel

pub fn static_crt(&mut self, static_crt: bool) -> &mut Config

Configures whether the /MT flag or the /MD flag will be passed to msvc build tools.

This option defaults to false, and affect only msvc targets.

pub fn build_arg<A: AsRef<OsStr>>(&mut self, arg: A) -> &mut Config

Add an argument to the final cmake build step

pub fn env<K, V>(&mut self, key: K, value: V) -> &mut Config where
    K: AsRef<OsStr>,
    V: AsRef<OsStr>, 

Configure an environment variable for the cmake processes spawned by this crate in the build step.

pub fn build_target(&mut self, target: &str) -> &mut Config

Sets the build target for the final cmake build step, this will default to "install" if not specified.

pub fn uses_cxx11(&mut self) -> &mut Config

Alters the default target triple on OSX to ensure that c++11 is available. Does not change the target triple if it is explicitly specified.

This does not otherwise affect any CXX flags, i.e. it does not set -std=c++11 or -stdlib=libc++.

pub fn always_configure(&mut self, always_configure: bool) -> &mut Config

Forces CMake to always run before building the custom target.

In some cases, when you have a big project, you can disable subsequents runs of cmake to make cargo build faster.

pub fn very_verbose(&mut self, value: bool) -> &mut Config

Sets very verbose output.

pub fn build(&mut self) -> PathBuf

Run this configuration, compiling the library with all the configured options.

This will run both the build system generator command as well as the command to build the library.
