FindMPI: do not detect `-framework` as a compile flag (!6467) · Merge requests · CMake / CMake

Ben Boeckel requested to merge ben.boeckel/cmake:FindMPI-framework-not-a-compile-flag into master Aug 19, 2021

MPICH 3.4.2 now reports -framework OpenCL as one of its compilation flag. The compile flag extraction is seeing it as a generic -f flag and misses its argument. This ends up with a compile option of -framework which eats the next flag (and may be very important).

It does not seem that passing -framework as a link flag is necessary at this time, so that is being actively ignored for now.

Fixes: #22555 (closed)
