try_compile: Propagate platform variables in project-mode too (!7265) · Merge requests · CMake / CMake

Brad King requested to merge brad.king/cmake:try_compile-project-platform-vars into master May 16, 2022

Add policy CMP0137 to propagate both our builtin variables and those listed by CMAKE_TRY_COMPILE_PLATFORM_VARIABLES to try_compile whole-project builds.

Also add a CMAKE_TRY_COMPILE_NO_PLATFORM_VARIABLES variable to suppress this behavior for either signature.

Fixes: #23219 (closed)
