Brad King	ec08bc1752	CheckIPOSupported: Compile check using flags of calling project ... Forward `CMAKE_<LANG>_FLAGS` and `CMAKE_<LANG>_FLAGS_DEBUG` from the calling project into the test project. The set of flags may affect the availability of IPO support. Since this may change the result of the check for existing projects, add a policy for compatibility. This was discovered after commit 5fcadc481e (MSVC: Default to -ZI instead of /Zi for x86 and x64, 2022-05-24) introduced policy CMP0138 to switch our default for MSVC's debug info flag. The `-ZI` flag is incompatible with the `-GL` flag used for IPO, so CMP0138 was reverted pending future work on an alternative solution. Re-use the CMP0138 policy number for this change to CheckIPOSupported instead. Fixes: #23607	2022-06-10 09:12:43 -04:00
Brad King	7d73e88d3a	MSVC: Revert "Default to -ZI instead of /Zi for x86 and x64" ... Revert commit 5fcadc481e (MSVC: Default to -ZI instead of /Zi for x86 and x64, 2022-05-24). The `-ZI` flag is incompatible with the `-GL` flag used for IPO, and so is not an unconditionally better default. Revert the change pending future design of a first-class setting for MSVC debug info format that can be automatically reconciled with IPO settings. That commit introduced policy CMP0138, but we already have later policy numbers used too. Leave placeholder text to avoid policy renumbering. Issue: #23607, #10189	2022-06-09 12:24:33 -04:00
