# This module include crossplatform toolchains by target platform.
# To select target platform set the TARGET_PLATFORM_TOOLCHAIN define.
# Availabel platforms:
# * wasm32
# * win32-g++
# * win64-g++
#
# Note
# For add full support of the wasm32 build you shold use the initWasmSupport method. This method prepare static build for wasm executable and qt resources.
#
# initWasmSupport arguments:
#  * name - This is name of your initialize targets. You can set it as a CMAKE_PROJECT
#  * deployFile - This is path to the deploy file of the cqtdepoyer tool. Use it for deploy your site.
