 ===== Cross Compilation =====
-A compiler that runs on one platform and generates code for another platform is called a [[https://en.wikipedia.org/wiki/Cross_compiler | cross compiler]]. We encourage to use our prebuilt software development kits (SDK) with built-in cross compiler. This SDK is installed on the host and contains exactly the same environment as is present on the target.
+A compiler that runs on one platform and generates code for another platform is called a [[https://en.wikipedia.org/wiki/Cross_compiler | cross compiler]]. We encourage to use our prebuilt software development kits (SDK) with built-in cross compiler. This SDK has to be installed on the host and contains exactly the same environment as is present on the target.
+If you don't use an SDK, you have to make sure to manually specify a cross compiler. EEROS uses CMake to build the code. By default CMake does not use a cross compiler. To tell CMake to use a cross compiler you have to supply the CMAKE_TOOLCHAIN_FILE option when generating the build files:
+<code>
+$ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/toolchain-file.cmake path/to/source/directory
