Do not expand variables in target source entries.
|
|
|
|
CMake 2.8.12 and lower performed an extra layer of variable expansion
|
|
when evaluating source file names::
|
|
|
|
set(a_source foo.c)
|
|
add_executable(foo \${a_source})
|
|
|
|
.. note: no cmake highlighting since this syntax is deprecated
|
|
|
|
This was undocumented behavior.
|
|
|
|
The ``OLD`` behavior for this policy is to expand such variables when processing
|
|
the target sources. The ``NEW`` behavior for this policy is to issue an error
|
|
if such variables need to be expanded.
