[cmake-developers] Android variables

[Ruslan Baratov]

Hi,

I wonder if it's possible to introduce next variables describing Android
tools:
* C preprocessor. Similar to CMAKE_CXX_COMPILER the variable that will
contain the path to preprocessor. Example:
 * CMAKE_CXX_COMPILER =
<ndk-root>/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-g++
 * CMAKE_C_PREPROCESSOR =
<ndk-root>/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-cpp
* ANDROID_TOOLCHAIN_MACHINE_NAME. In fact I'm not sure what this
variable mean but it's an important part of move from taka-no-me
toolchain to CMake 3.7. I guess it's like
 * CMAKE_CXX_COMPILER =
<ndk-root>/toolchains/${ANDROID_TOOLCHAIN_MACHINE_NAME}-4.9/prebuilt/linux-x86_64/bin/${ANDROID_TOOLCHAIN_MACHINE_NAME}-g++

Of course if I'm not missing something and they are not already somewhere :)
