[OpenWalnut-Dev] How to integrate the PCL library to a module toolbox?

[Sebastian Eichelbaum]

Hi.

Christof is right. The code he posted shows that the NA-online project uses CMake's FIND_PACKAGE function. This should work well in most cases, but usually requires you to install the lib system-wide. If you do not want this, you can use FIND_PATH instead. You can see an example in the OpenWalnut code under tools/cmake/Findniftilib.cmake. This allows you to embed "foreign" code into your source paths.

Cheers,
Sebastian
