问题
I used cmake and I was able to build a C::B project. But Compiling the Assimp.cbp file raised a bunch of errors. Is there someone experimented in compiling assimp with mingw64 under w10 for C::B to send me clues ? Thks in advance. Here are the log errors :

Here's how I build it under MSYS2 with MinGW-w64:

Replace /usr/local with the destination folder that you need.
I was not successful building it with -DASSIMP_BUILD_ASSIMP_TOOLS:BOOL=ON though.
回答2:
I don't know assimp library, but if you use msys2, you can install the complete package (dynamic and static library and all the header files) with the command:
pacman -S mingw-w64-x86_64-assimp.
回答3:
As far as I know the tools are currently not working with this compiler. I need to check that.
