Most Xiph.Org projects can be cross compiled for native platforms. You can either use the autotools build system provided, or use a custom build system or IDE with the sources directly.

==Using Autotools==
Autotools generally only works with GCC-like toolchains.

First, make sure your $PATH environment variable contains the path to your toolchain binaries (arm-none-eabi-gcc or similar).

You will need an install path to put the final headers and libraries. Your main project might have a spot already, or you can create a directory:
mkdir install

Then, run the configure script with the host triple, install directory, and necessary CFLAGS:

./configure --host=arm-none-eabi --prefix=/home/thomas/sandbox/opus/install CFLAGS="-mcpu=cortex-a15 --specs=nosys.specs"

You might also need extra options specific to the library you are compiling.

Then,
make
make install

You should now have a lib/ and include/ dir under your installation prefix, containing the built library and header files.

==Using your own build system==
This is highly dependent on the project you are compiling. Many have simple Unix makefiles for reference.
