[CMake] Can't set CMAKE_Fortran_FLAGS ?

[David Cole]

When you:
SET(CMAKE_Fortran_FLAGS "-fno-backslash")

it does not affect the cache... it is only a local override of the cache
value.

It should take effect in the generated project/make files, though.

If you want to see it in the cache editor, you have to use "FORCE" with SET.
(Although if you do that, you cannot change it from the cache editor.....)


HTH,
David
