depends/README.md

 +### Usage
 +
 +To build dependencies for the current arch+OS:
 +
 +    make
 +
 +To build for another arch/OS:
 +
 +    make HOST=host-platform-triplet
 +
 +For example:
 +
 +    make HOST=x86_64-w64-mingw32 -j4
 +
 +A prefix will be generated that's suitable for plugging into Bitcoin's
 +configure. In the above example, a dir named x86_64-w64-mingw32 will be
 +created. To use it for Bitcoin:
 +
 +    ./configure --prefix=`pwd`/depends/x86_64-w64-mingw32
 +
 +Common `host-platform-triplets` for cross compilation are:
 +
 +- `i686-w64-mingw32` for Win32
 +- `x86_64-w64-mingw32` for Win64
 +- `x86_64-apple-darwin11` for MacOSX
 +- `arm-linux-gnueabihf` for Linux ARM 32 bit
 +- `aarch64-linux-gnu` for Linux ARM 64 bit
 +
 +No other options are needed, the paths are automatically configured.
 +
 +Dependency Options:
 +The following can be set when running make: make FOO=bar
 +
 +    SOURCES_PATH: downloaded sources will be placed here
 +    BASE_CACHE: built packages will be placed here
 +    SDK_PATH: Path where sdk's can be found (used by OSX)
 +    FALLBACK_DOWNLOAD_PATH: If a source file can't be fetched, try here before giving up
 +    NO_QT: Don't download/build/cache qt and its dependencies
 +    NO_WALLET: Don't download/build/cache libs needed to enable the wallet
 +    NO_UPNP: Don't download/build/cache packages needed for enabling upnp
 +    DEBUG: disable some optimizations and enable more runtime checking
 +    HOST_ID_SALT: Optional salt to use when generating host package ids
 +    BUILD_ID_SALT: Optional salt to use when generating build package ids
 +
 +If some packages are not built, for example `make NO_WALLET=1`, the appropriate
 +options will be passed to bitcoin's configure. In this case, `--disable-wallet`.
 +
 +Additional targets:
 +
 +    download: run 'make download' to fetch all sources without building them
 +    download-osx: run 'make download-osx' to fetch all sources needed for osx builds
 +    download-win: run 'make download-win' to fetch all sources needed for win builds
 +    download-linux: run 'make download-linux' to fetch all sources needed for linux builds
