[SOLVED] Troubles with CMake and Assimp

Issue

I have the latest assimp source code (5.0.1 release), I have built it with CMake and installed using cmake --install. Now I am trying to add it to my CMake project: find_package(Assimp REQUIRED Assimp) - at this moment it configures fine. The problems started when I tried to add

target_link_libraries(
    MyProj PRIVATE
    Assimp::Assimp
)

And I get the following error:

[cmake]   target "MyProj" links to target "Assimp::Assimp" but the target
[cmake]   was not found.  Perhaps a find_package() call is missing for an IMPORTED
[cmake]   target, or an ALIAS target is missing?

After some research, I've tried target_link_libraries(MyProj PRIVATE ${ASSIMP_LIBRARIES}), this time I got a compile error, and when I displayed the value of the ${ASSIMP_LIBRARIES} variable (command: message("${ASSIMP_LIBRARIES}")) I got: assimp-vc142-mt.dll - it contains .dll name, even without full path. Have a lot of troubles with assimp, could anyone suggest a solution?


Solution

Without having any knowledge of assimp, I think what you want is this:

target_link_libraries(MyProj PRIVATE assimp::assimp)

As far as I know, CMake target names are case sensitive and the assimp::assimp alias target is created here with lowercase a.
