Honor link flags in :command:`try_compile` source-file signature.
|
|
|
|
The :command:`try_compile` command source-file signature generates a
|
|
``CMakeLists.txt`` file to build the source file into an executable.
|
|
In order to compile the source the same way as it might be compiled
|
|
by the calling project, the generated project sets the value of the
|
|
:variable:`CMAKE_<LANG>_FLAGS` variable to that in the calling project.
|
|
The value of the :variable:`CMAKE_EXE_LINKER_FLAGS` variable may be
|
|
needed in some cases too, but CMake 3.1 and lower did not set it in
|
|
the generated project. CMake 3.2 and above prefer to set it so that
|
|
linker flags are honored as well as compiler flags. This policy
|
|
provides compatibility with the pre-3.2 behavior.
|
|
|
|
The ``OLD`` behavior for this policy is to not set the value of the
|
|
:variable:`CMAKE_EXE_LINKER_FLAGS` variable in the generated test
|
|
project. The ``NEW`` behavior for this policy is to set the value of
|
|
the :variable:`CMAKE_EXE_LINKER_FLAGS` variable in the test project
|
|
to the same as it is in the calling project.
|
|
|
|
If the project code does not set the policy explicitly, users may
|
|
set it on the command line by defining the
|
|
:variable:`CMAKE_POLICY_DEFAULT_CMP0056 <CMAKE_POLICY_DEFAULT_CMP<NNNN>>`
|
|
variable in the cache.
|
|
|
|
This policy was introduced in CMake version 3.2. 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:`CMAKE_POLICY_WARNING_CMP0056 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
|
|
variable to control the warning.
