Hi All, Say I have a CMakeLists.txt that does
add_definitions(-DFOO=1) add_subdirectory(bar) and in bar the CMakeLists.txt does add_definitions(-DFOO=2) The intention being that the code in the subdirectory needs the different definition of FOO. Is there a straightforward way to temporarily override the -DFOO? That is, when we go back up to the parent that -DFOO=1 now has effect? My naive attempt above means that -DFOO=1 -DFOO=2 ends up in the compiler arguments which causes things to break (the compiler doesn't like FOO being redefined like that). Any hints? thanks b.
