Building Qt Android app with an external lib (Assimp)

[Sergobot]

Hello everybody
I have built assimp for Android but can't use it in my project. Searching in Google doesn't help. I tried adding this code to my .pro file:

android {
    INCLUDEPATH += $$PWD/../3rdparty/assimp-3.1.1/include
    DEPENDPATH += $$PWD/../3rdparty/assimp-3.1.1/include

    ASSIMP_PATH = $$PWD/../3rdparty/assimp-3.1.1/
    assimp.path = /libs/armeabi-v7a
    assimp.files = $$ASSIMP_PATH/libassimp.so
    INSTALLS += assimp
}

but it doesn't work.
So, how to add an external Android library to a Qt project?

Hi and welcome to devnet,

What exactly doesn't work ?

If it's linking you are missing

LIBS += -lassimp

in your pro file

Hello SGaist,
I added
LIBS += -L$$PWD/../3rdparty/assimp-3.1.1/ -lassimp
to my .pro but still can't compile it because compiler gives me the same error as before:
error: assimp/Importer.hpp: No such file or directory #include "assimp/Importer.hpp"
which is really strange because the INCLUDEPATH variable is right and works when I use it for building for other platforms.
Adding
LIBS += -lassimp
doesn't help too

Are you sure that $PWD/../3rdparty/assimp-3.1.1/include point to the right location ?

[Sergobot]

Yes, of course, it works when I build for other platforms.

[SGaist]

Are you also using $PWD/../3rdparty/assimp-3.1.1/include for the other platforms ?

[Sergobot]

Almost yes.
Now I use $$PWD/../3rdparty/assimp-3.1.1/include(2x '$') for all platforms, including Android, but I still can't build my .pro for it. For using $PWD I should set it to the right value in Projects->Build Environment, for each kit separately, right?
