# What?:
# android-cmake toolchain searches for NDK/toolchain in the following order:
# Make sure to do the following in your scripts:
# SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}" )
# SET( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}" )
-# The flags will be prepopulated with critical flags, so don't loose them.
-# Also be aware that toolchain also sets configuration-specific compiler
-# flags and linker flags.
+# The flags will be prepopulated with critical flags, so don't loose them.
+# Also be aware that toolchain also sets configuration-specific compiler
+# flags and linker flags.
#
# ANDROID and BUILD_ANDROID will be set to true, you may test any of these
# variables to make necessary Android-specific configuration changes.
#
-# Also ARMEABI or ARMEABI_V7A or X86 will be set true, mutually exclusive.
-# NEON option will be set true if VFP is set to NEON.
+# Also ARMEABI or ARMEABI_V7A or X86 or MIPS will be set true, mutually
+# exclusive. NEON option will be set true if VFP is set to NEON.
#
# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android
# libraries will be installed.
# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME}
# (depending on the target ABI). This is convenient for Android packaging.
