QCC compiler id for the qcc drivers on QNX.
CMake 3.0 and above recognize that the QNX qcc compiler driver is
different from the GNU compiler.
CMake now prefers to present this to projects by setting the
CMAKE_<LANG>_COMPILER_ID variable to
GNU. However, existing projects may assume the compiler id for
QNX qcc is just
GNU as it was in CMake versions prior to 3.0.
Therefore this policy determines for QNX qcc which compiler id to
report in the :variable:
CMAKE_<LANG>_COMPILER_ID variable after
<LANG> is enabled by the :command:
enable_language command. The policy must be set prior
to the invocation of either command.
The OLD behavior for this policy is to use the
GNU compiler id
for the qcc and QCC compiler drivers. The NEW behavior for this policy
is to use the
QCC compiler id for those drivers.
This policy was introduced in CMake version 3.0. Use the
cmake_policy command to set this policy to OLD or NEW explicitly.
Unlike most policies, CMake version |release| does not warn
by default when this policy is not set and simply uses OLD behavior.
See documentation of the
variable to control the warning.
