#  This script calls cmake and ninja to compile OpenThread for the given platform.
#
#  Compile with default build options:
#
#      script/cmake-build ${platform}
#
#  Compile with the specified build option enabled:
#
#      script/cmake-build ${platform} -D${option}=ON
#
#  Compile with the specified build option disabled that already enabled by default:
#
#      script/cmake-build ${platform} -D${option}=OFF
#
#  Compile with the specified ninja build target:
#
#      OT_CMAKE_NINJA_TARGET="ot-cli-ftd" script/cmake-build ${platform}
#
#  Compile with the specified build directory:
#
#      OT_CMAKE_BUILD_DIR="./build/temp"  script/cmake-build ${platform}
#
#  Examples:
#
#      script/cmake-build simulation
#
#      script/cmake-build simulation -DOT_FULL_LOGS=ON -DOT_CHANNEL_MANAGER=OFF
#
#      OT_CMAKE_NINJA_TARGET="ot-cli-mtd" OT_CMAKE_BUILD_DIR="./build/temp" script/cmake-build simulation -DOT_FULL_LOGS=ON -DOT_CHANNEL_MANAGER=OFF
