libBullet link errors when rebuilding

cocos2d-x
1

I have an issue when I rebuild my project, without first cleaning the solution (error log below). I am using cmake with vs2017 and the latest github commit. If I first clean the solution, then the link error does not happen.

I have tried:

set(CMAKE_SUPPRESS_REGENERATION true)

but it makes no difference.

Anyone else seen this?

OK, so it looks like this was caused by me dicking about with CMAKE_CONFIGURATION_TYPES in order to allow both Debug and Release builds:

set(CMAKE_CONFIGURATION_TYPES "Debug;Release" CACHE STRING "" FORCE)

If I remove this then it’s working fine, however I am locked into Debug only mode, which is obviously a problem. Why is it locked to Debug only mode?

So I actually read the documentation about CMake and Cocos2d-x and that told me about the CMAKE_BUILD_TYPE variable which can be set from the cmake command line in order to generate a debug or release build configuration. This is a bit different to what I’m used to, but it works!
