So I've set up a CMakeLists.txt script (runs fine), which sets up my project : Problem is when I run the makefile, everything runs fine, until it prints me :

PS : I installed assimp like this (I'm on linux/ubuntu) : sudo apt-get install libassimp-dev; The library is for sure well installed; because I laready used it, in the same project using code::blocks !

Linking CXX executable Test
CMakeFiles/Test.dir/src/Mesh.cpp.o: In function `Mesh::Mesh(char const*)':
Mesh.cpp:(.text+0x1db): undefined reference to `Assimp::Importer::Importer()'

Here is my CMakeLists.txt : 

CMAKE_MINIMUM_REQUIRED(VERSION 2.8)
project(Test)

set(CMAKE_CXX_FLAGS "-std=c++11")

    #I won't list cpp files, bcause there are a lot !

I guess the right answer is more:

target_link_libraries(${PROJECT_NAME} ${ASSIMP_LIBRARIES})

LIBRARIES not LIBRARY

Please try to use 

target_link_libraries(${PROJECT_NAME} ${ASSIMP_LIBRARIES})

I am not sure, if the library will be linked to the right executable.

  • Nope, still not working.... But I've got my assimp folder next to my cmake folder, how can I specify the include path to it ?

  • Use INCLUDE_DIRECTORIES( <include_dir> ) to specify it.

  • ok, but I should list all the assimp headers, or is there a way to include everything in assimp ?

  • Try to use the public heaers, which are in include. All pricate headers you will find in the code area. And of course only include public header which you need to use.
