Hi Brad,
Apologies, I didn’t look closely enough/didn’t understand that the discovery
modules would be under influence of CMAKE_OSX_DEPLOYMENT_TARGET set from the
CMakeFiles.txt, makes total sense now that you said that.
This is the doxygen project, I just did a git clone of their latest. Their
CMakeLists.txt file is the problem, it has:
if (${CMAKE_SYSTEM} MATCHES "Darwin")
set(CMAKE_CXX_FLAGS "-Wno-deprecated-register -mmacosx-version-min=10.5
${CMAKE_CXX_FLAGS}")
set(CMAKE_C_FLAGS "-Wno-deprecated-register -mmacosx-version-min=10.5
${CMAKE_C_FLAGS}”)
...
endif()
If I'm going to put that in my CMakeList.txt then I don’t think CMake can
really stop me from shooting myself in the foot.
Cheers,
- James
