This option was added by commit v2.8.12~138^2 (Add
cmake_reset_check_state() macro, 2013-07-28) but has never worked.
Fix the implementation to refer to macro arguments properly (not as
normal variables).
Fixes: #17048
This commit fixes the following warning originally introduced in
1325260 (Add macros cmake_push/pop_check_state() as discussed on the list.)
Argument not separated from preceding token by whitespace.
This patch adds two macros cmake_push_check_state() and
cmake_pop_check_state(), which can be used to save and restore
the contents of the CMAKE_REQUIRED_xxx variables.
