I'm trying to create a NewConfiguration for my project:

set (CMAKE_CONFIGURATION_TYPES "Release;RelWithDebInfo;Debug;NewConfiguration" CACHE STRING "Configurations" FORCE)

But when I run CMake, I have multiple errors:

CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_SHARED_LINKER_FLAGS_NEWCONFIGURATION CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly. Missing variable is: CMAKE_CXX_FLAGS_NEWCONFIGURATION

I think I'm missing something...

I also followed CMake FAQ:

 if(CMAKE_CONFIGURATION_TYPES) set(CMAKE_CONFIGURATION_TYPES Release RelWithDebInfo Debug NewConfiguration) set(CMAKE_CONFIGURATION_TYPES "${CMAKE_CONFIGURATION_TYPES}" CACHE STRING "Reset the configurations to what we need" FORCE) endif()

But same errors...

EDIT:

If I do:

 SET( CMAKE_CXX_FLAGS_PLAYERVIEWER "-Wall -Wabi" CACHE STRING "Flags used by the C++ compiler during maintainer builds." FORCE ) SET( CMAKE_C_FLAGS_PLAYERVIEWER "-Wall -pedantic" CACHE STRING "Flags used by the C compiler during maintainer builds." FORCE ) SET( CMAKE_EXE_LINKER_FLAGS_PLAYERVIEWER "-Wl,--warn-unresolved-symbols,--warn-once" CACHE STRING "Flags used for linking binaries during maintainer builds." FORCE ) SET( CMAKE_SHARED_LINKER_FLAGS_PLAYERVIEWER "-Wl,--warn-unresolved-symbols,--warn-once" CACHE STRING "Flags used by the shared libraries linker during maintainer builds." FORCE ) set (CMAKE_CONFIGURATION_TYPES "Release;RelWithDebInfo;Debug;PlayerViewer" CACHE STRING "Configurations" FORCE)

It creates the new configuration, but I can not compile. I think flags are not correct. I am using Visual Studio 2008.

Thank you :)

I've just created 6 or 7 new configurations for VS2008 with cmake 2.8.4 (now it is days or even hours from 2.8.5 release) for simple hello world project.

The reason why your attemps failed what flags are inccorect e.g. they must be /MDd no -MDd You notation will work for GCC based compilers, not for VS.

What I recommend you is to get closest flags set and modify it then

set(CMAKE_CXX_FLAGS_FOO ${CMAKE_CXX_FLAGS_DEBUG}) # .. modifiy it - add or remove flags

also i noticed that cmake sometimes does not actually write to .sln or it is not always reloaded (well, I am running win7 on VirualBox maybe it is source of issues).

what i did is the following -

file(GLOB WILL_REMOVE "${CMAKE_CURRENT_BINARY_DIR}/*.vcproj") execute_process(COMMAND ${CMAKE_COMMAND} -E remove -f ${WILL_REMOVE}) file(GLOB WILL_REMOVE "${CMAKE_CURRENT_BINARY_DIR}/*.sln") execute_process(COMMAND ${CMAKE_COMMAND} -E remove -f ${WILL_REMOVE}) file(GLOB WILL_REMOVE "${CMAKE_CURRENT_BINARY_DIR}/*.user") execute_process(COMMAND ${CMAKE_COMMAND} -E remove -f ${WILL_REMOVE})

at least it reloads files :)

however, sometimes i need to run cmake 2 or 3 times to see new configuration at visual studio (can be virtual box, cmake or visual studio bug - have no idea about it).

But, anyway, after 2 or 3

cmake ..

It WORKS!!!!

The "run several times ..." might be a visual studio problem, not a CMake one. Basically my experience is, that in VS2005 and 2008 (didn't use 2010 yet) reloading projects often does not work, so I always close the solution and reopen it.

Despite the CMake FAQ, looks like there is something still a bit unimplemented for this feature request. There is even an open issue for it:

http://www.cmake.org/Bug/view.php?id=5811

Monitor that bug in the CMake bug tracker to be notified as things are updated.
