Tim, thank you.
Compiler and environment specific things become defined during "project" command execution. It is too late to check if it is set afterwards because it actually IS SET. I assume you are lucky and default value for CMAKE_Fortran_FLAGS_RELEASE is empty, isn't it? So the tricky point is to place customization code in proper place. In my case == set(CMAKE_CXX_FLAGS_DEBUG "-g -wall" CACHE STRING "" ) == works perfectly if put at the top of CMakeLists.txt 28.04.2011, 19:23, "Tim Gallagher" <[email protected]>: > We do this: > > if(NOT CMAKE_Fortran_FLAGS_RELEASE) > set(CMAKE_Fortran_FLAGS_RELEASE "-O2 -xhost" CACHE STRING "" FORCE) > endif() > > In other words, if the flags haven't been set yet (initial start up), set > them to what we want.
