The droplist is really cool! Can't understand why it's not the default this way.
https://cmake.org/cmake/help/v3.0/variable/CMAKE_CONFIGURATION_TYPES.html says
"This has reasonable defaults on most
platforms...", but when I message(${CMAKE_CONFIGURATION_TYPES}) it is empty.
Why that?
That code also does not seem to set the default:
if(NOT CMAKE_CONFIGURATION_TYPES)
set(CMAKE_CONFIGURATION_TYPES Debug Release RelWithDebInfo)
endif()
set(CMAKE_BUILD_TYPE Debug CACHE STRING "Build Type")
set_property(CACHE CMAKE_BUILD_TYPE PROPERTY STRINGS
${CMAKE_CONFIGURATION_TYPES} )
So the first commands set the cached value of the string "Build type". The
second commands sets the property STRINGS of
the variable CMAKE_BUILD_TYPE. Is that correct?
# if (NOT CMAKE_BUILD_TYPE)
# set(CMAKE_BUILD_TYPE Debug)
Uncommenting this sets the default non builds with cmake, but not on ccmake (at
least not in the GUI).
# endif()
message(STATUS "Build configuration: " ${CMAKE_BUILD_TYPE})
Best Thanks,
Florian
