Bug 4117

Summary: SDL_CMAKE_DEBUG_POSTFIX can not take an empty string
Product: SDL Reporter: Yuriy Levchenko <irov13>
Component: buildAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: tesch1
Version: 2.0.10Keywords: target-2.0.12
Hardware: x86_64   
OS: Windows 7   

Description Yuriy Levchenko 2018-03-25 18:12:00 UTC 
If I set this option to "", then I get an error in this code

set_target_properties(SDL2main PROPERTIES DEBUG_POSTFIX ${SDL_CMAKE_DEBUG_POSTFIX})

add a check that this variable exists, like this

if(SDL_CMAKE_DEBUG_POSTFIX)
  set_target_properties(SDL2main PROPERTIES DEBUG_POSTFIX ${SDL_CMAKE_DEBUG_POSTFIX})
endif()

Thanks!

I've also just stumbled upon this bug.

Another possible fix would be to just add quotes around the variable expansion:

set_target_properties(SDL2main PROPERTIES DEBUG_POSTFIX "${SDL_CMAKE_DEBUG_POSTFIX}")

This occurs on lines 1795, 1825, 1865 of CMakeLists.txt

This is fixed in https://hg.libsdl.org/SDL/rev/8cd53e2d31a5, thanks!
