ceclipseeclipse-cdt
I created a static library which i'm including in another C++ eclipse cdt project.
Everything is compiled correctly once i change the build settings accordingly, but the editor still doesn't recognize the types which were declared in the static library, marking many red squiggly marks, etc.
Is there any way to make the eclipse editor search in the same places as the compiler? It is a very big visual nuisance to say the least.
An alternative approach would be to extract features (keypoints) using the scale-invariant feature transform (SIFT) or Speeded Up Robust Features (SURF).
You can find a nice OpenCV code example in Java, C++, and Python on this page: Features2D + Homography to find a known object
Both algorithms are invariant to scaling and rotation. Since they work with features, you can also handle occlusion (as long as enough keypoints are visible).

The processing takes a few hundred ms for SIFT, SURF is bit faster, but it not suitable for real-time applications. ORB uses FAST which is weaker regarding rotation invariance.
You have to add the library name without lib and .a in Libraries (-l) and adding the path in Libraries search path (-L).
However, this question is resolved also in this stack.
Also in this site you can find a lot of usefull information and the explanation on how include linking library.

As reported in the documentation:
Q. How do I add a static library file to a project? (Files such as libmtm.a)
A. First you will need to copy the file into your Eclipse project. You can do that by simply dragging it into the project folder in the "Project Explorer" tree in Eclipse. To link the library (A static library is used similarly to an object file):
- Open Project, Properties.
- In that dialog select "C++ Build, Settings".
- Under the Tool Settings tab choose "Linker" or "MinGW C Linker" or equivalent and under that select "Libraries".
- Under "Libraries" press the "Add..." button (the green cross) and write the name of the library without the "lib" prefix and ".a" suffix. e.g. in order to link the library file libmtm.a write "mtm".
- Under "Library search path" press the "Add..." button, select workspace and select the project.

I had a rather similar problem. The problem was that in a project, whenever I included a standard library,
stdio.hfor example, eclipse did not recognize any of the functions and macros defined there or could recognize some of them. To solve the problem, all I needed to do was to refresh the indexer. In order to refresh the indexer, right click on the project and select indexer->rebuild.
