# CMake Toolchain file for crosscompiling on ARM.

# This can be used when running cmake in the following way:
# cd build/
# cmake .. -DCMAKE_TOOLCHAIN_FILE=../cross-arm-linux-gnueabihf.cmake
#
set(CROSS_PATH /opt/libwebsockets_android/android-toolchain-arm)
# Target operating system name.
set(CMAKE_SYSTEM_NAME Android)
# Target build dynamic libs.
set(BUILD_SHARED_LIBS ON)
# Name of C compiler.

# Different build system distros set release optimization level to different
# things according to their local policy, eg, Fedora is -O2 and Ubuntu is -O3
# here. Actually the build system's local policy is completely unrelated to
# our desire for cross-build release optimization policy for code built to run
# on a completely different target than the build system itself.
#
# Since this goes last on the compiler commandline we have to override it to a
# sane value for cross-build here. Notice some gcc versions enable broken
# optimizations with -O3.
